OK - disregarding my notational idiosyncracies for this hexany I get Blackjack steps 3, 7, 8, 12, 17,
19.

Got this one now from your lattice; here's one example, centred on step 8 :-

3 15 6

17 8 20

Got this one too - 17, 8, 3, 13, 20. Or 15, 6, 1, 11, 18. And so on.

My first mistake is that I'm not using the lattices to do my basic workings. The second is that I'm not
consulting Dave Keenan's cut and paste charts.

Thanks for being patient

Excellent! That's one. It also appears in at least four other
positions in the Blackjack scale. Can you find them?

Great! Can you find the other one?

Correction to my previous post: if you want one of these to have A as
tonic, then you need to center the Blackjack scale on either

G raised by 1/4 tone

or

G lowered by 1/3 tone.

Yes, from your multicoloured lattice I can see them popping out all over the place. For example,
there's one at G> , B[ , D> , Db^ , Ab^ , F in your notation. What an eye opener!

Yes, by scale steps I have

Thanks again. I'd be better working from scale steps or from your notation for the moment. Then
I'll deal with notation when I have everything tuned up.

I've noticed that two adjacent hexanies share two common tones, Ab^ and F in your notation.
Consequently two of my 6 string zithers could be tuned to one hexany each, using the common tones
to modulate. As the zithers have a nice long sustain, this would work well with the kind of music
I'm writing.

Yo! - 4: 5: 6: 7: 9 is 15, 1, 6, 11, 18 or, by your notation; A[ , C> , E[ , Gb^ (the
tetrahedron) and B[. With another on Bb< as a root. Now I understand the big discussions on
stellation and geometry in general. Once you understand your shapes on a lattice they remain
constant from lattice to lattice given the same axes.

4: 6: 7: 9: 11 is, for example, 9, 0, 5, 12, 18 in your notation F, C, Eb< , G, B[ . The 11 and
the 4 are at polar opposites of a hexany for my future reference.

You certainly seem to be getting the picture! It would have been even
easier to find these (and all the other examples of these chords) had
you worked from Dave's slide rule rather than my lattice (though of

Hi Paul!

Well, since I basically have been using your lattice to find common-
tone blackjack harmonies, now I'm naturally wondering what I could be
doing with Dave's slide rules that I can't do with your lattice...

Perhaps this is an obvious question with an obvious answer, but it
isn't immediately coming to me...

Well, it's easy to see the 7-limit tetrads on my lattice, but what
about 9-limit and 11-limit harmonies (some of which were included in
my keyboard charts)? With the slide rule, one can immediately see
whether a given chord type will occur in Blackjack, and if it does,
where, and how many times.

The advantage of the lattice is that one can immediately see all the
possibilities for common-tone chord changes (at least between 7-limit
tetrads). To do that with the slide rule would involve having several
different "strips" and moving them around with respect to one
another -- not as elegant, and not as conducive to long-range
planning.

Oh, are you still using the normal 7-limit lattice? I find my
7-limit/neutral third lattice much easier to use than either. If anybody
still hasn't caught on to it, the explanation starts at
<http://x31eq.com/lattice.htm> or a link from there or
something.

You could get slide rule-like behaviour on a 2-D lattice by using a
plastic sheet, writing on it, and moving it over the lattice. OHP
transparencies would probably work. Assuming you can't picture it your
head.

That would be great in conjunction with your lattice, Graham --
especially since many of the 11-limit connections are not shown on it.

The difference is that the scale is a chain of generators, so when
laid out 1-dimensionally, you can immediately see whether a
particular chord will "fit" and if so, how many times. On a plastic
sheet, you could slide it around and potentially fail to see the
point where it "fits".

Ummm. If I remember correctly, Graham's 2D version of this 11-limit
lattice was a bit "scrunched up" and it was hard to work with...

Anybody have the post# on the list of that... it's someplace here in
the archive...

Maybe with the transparencies this problem would be solved.

Although, at the moment, I am busy working with Paul's 7-limit
lattices and there is much to explore here, I would enjoy trying
to "mess around" with the 11-limit ones and trasparencies.

If anyone actually *produces* this, I would be more than willing to
pay something for the trouble, including postage.

Please write to me off list if this actually happens, since I think
this could be quite valuable for future blackjack composing...

Thanks!

Well, as you may know if you've been following, Alison within the
last couple of days has been able to find 9- and 11-limit chords on
_my_ lattice.

9 is just 3*3. The 11 Odentity can be found directly below the
corresponding root -- the two are at opposite ends of a hexany. For
example, an 11/8 above F is B[. This works because 384/385 vanishes
in MIRACLE and 72-tET.

As you can see from the notation itself, this is a fourth plus a
quartertone, or an 11/8!

Hmmm... well, then, it certainly seems like your lattice can be used
to find at least *some* 11 limit stuff.

Now a confession to make:

I've been having a very hard time making "compound" chords in
blackjack. By "compound" chords, I mean "big" chords having, let's
say, 8 notes.

The lattice works well for devising various 4-pitch "common note"
progressions and, actually, some of them are working quite well in
retrograde, too. Naturally this is all subject to taste (hopefully).

However, in the construction of these "magnum" chords, I am stymied.

In my imagination, that was the reason for putting the *two* TX81Z's
together. I was imagining glorious 8-part chords with elements
shifting in and out, all in astonishing just intonation harmony!

However, it's not quite working out that way. All the "big" chords
sound just terrible.

Any suggestions?? :)

Well, I was trying to develop extended ones using the "common tone"
methods only extending, naturally, from more than one common tone...

None were sounding too great. I can get you some specifics later,
but maybe I should just try some others first...

The first issue is voicing. A nice-sounding 8-tone chord in blackjack
is likely to require you to stretch your fingers out tremendously on
the keyboard, probably farther than physically possible :)

Now I'd guess, since you mention "'common tone' methods", that you
were probably trying to play three or more adjacent tetrads at a
time, yes?

In JI, this would tend to work best if the tetrads were in 3:2
relationships to one another. However, even then you get dissonant
intervals like 21:16 and 64:63 very early in the process. Some people
like these intervals in this kind of context . . . try a 6-note chord
like Bb< F< C< (left hand), G> D> A> (right hand). Notice the very
small "64:63" interval between Bb< and A> -- it can clash more or
less depending on how you voice it. Now complete the two Otonalities
by inserting D[ and A[ (look on the lattice to see what I mean by
that). Play around with voicing, and you have a nice big rich "JI" 8-
tone chord.

Now since we're not quite in JI, we should take advantage of certain
unison vectors, like the 225:224. You see, a lot of intervals on the
lattice that would be "dissonant" in JI become "consonant" because of
this. If you look at your own "Tuning Lab" page, you can see this
happening in some of the chords (search the page for 225:224). One
example is something I called the "magic chord" a while ago. In
Blackjack you can find it at Db^ F G Bv. Note that in order to see
all the consonant intervals in this chord (and I'm counting 9:8 as
consonant for this exercise), you have to locate at least one of the
notes in more than one place in the lattice. For example, you could
go from Db^ east-northeast to F, east to G, and northeast to Bv, but
you wouldn't see that Bv is consonant with the starting point Db^
unless you continued south-southwest from Bv to _another_ Db^.
Grouping together more notes in the vicinity, and voicing carefully,
a chord like Db^ F Ab^ G Bv Ev C might prove interesting to you, as
well as similar chords elsewhere on the lattice. 225:224 even helps
you if you try to produce some nice big 5-prime-limit chords, like
say the Ramos-inspired Eb< Bb< F< C< D[ A[ E[ B[ or D[ A[ E[ B[ C> G>
D> A>, since each of the three 45:32s is approximating 7:5 very well.

But perhaps what you really desire are 15-limit Otonalities --
8:9:10:11:12:13:14:15 chords. Then Blackjack is probably not your
answer, though 72-tET can still serve you well -- if you used a 5/72-
oct. generator instead of a 7/72-oct. generator, then a 43-tone MOS
would give you (approximations to) four 8:9:10:11:12:13:14:15 chords
and four 8:9:10:11:12:13:14:15 chords -- though 43 is more than twice
as many notes as Blackjack!

Hi Joseph. I figured we could look for some simple 7- and 8-note
harmonic series chords in Blackjack, and move on to polychords and
the like later.

Let's look at Dave Keenan's slide rule again:

2 9 16 23 30 37 44 51 58 65 0 7 14 21 28 35 42 49 56 63 70
5--------------7-----1-----------------3-----------------9-------11

I'll traslate into "our" note names, and to conserve space, I'll
write them vertically:

C D E E F G G A B B C D D E F G G A A B C
> [ b v b > [ b v b > [ < b b > [ <
< ^ < ^ v ^
5---------7---1-----------3-----------9------1
1

Let's include some of the simpler composite numbers within the 11-
prime limit (the fact that they're composite means they'll
provide "extra" consonance with the lower identities and with one
another):

C D E E F G G A B B C D D E F G G A A B C
> [ b v b > [ b v b > [ < b b > [ <
< ^ < ^ v ^
2-------------5---------7-1-1-------2---3-----------9-----1-----2
5 5 1 1 7

So now, by "sliding" the slide rule, we can find some nice big
harmonic-series-based chords in 72-tET. Please voice them from lowest
to highest for best results, though you can double or even triple the
lower notes in the chord, both upward and downward by octaves.

F< C< A[ D> E[ A> C> -- this is a 1:3:5:7:15:21:25 chord

Bb< F< D[ G> C< A[ D> -- this is a 1:3:5:7:9:15:21 chord

Eb< Bb< C> F< Ab^ D[ G> C< -- a 1:3:7:9:11:15:21:27 chord

(moving between these three chords should sound really strong: "V, I,
IV")

A[ E[ C> Gb^ B[ G> Db^ -- this is another 1:3:5:7:9:15:21 chord

D[ A[ E[ G C> Gb^ B[ -- this is a 1:3:9:11:15:21:27 chord --
the 21 (Gb^) might sound especially disconnected here since there's
no 7.

to "I" or "I" to "IV")

Gb^ Db^ Ev Ab^ C< F Bv -- this is a 1:3:7:9:11:15:21 chord

F C Eb< G B[ Ev Bb< -- another 1:3:7:9:11:15:21 chord

Try these out with different timbres, pay special attention to
voicing, and let be know what you think.

Well, this post sure proves that it's worth while to ask questions!
I see some more helpful posts "down the pike" which I will also get
to and experiment with. Thanks both Paul and Dave!

Well, Paul, actually the way I am working I have four notes on one
channel and four on *another* so they will be "overlaid" with the
sequencer and, hence, that's not a problem...

I was actually only trying to play a *couple* simultaneously, but I
chose some *lousy* ones right off the bat... probably I didn't do
enough thinking about what would work before I started... (That
usually might help... :) )

Umm, actually that came to me also after I was through with my first
experiments, but I didn't have time yet to try it out. I was also
initially "discouraged" with some of the "big chords" I found, so I
was doing other composing things with my piece for a while....

But, naturally, that would make sense, since it would be a similar
procedure to the building up of "polychords" in 12-tET... based on
the fifth...

*THAT IS FANTASTIC* I *LOVE* that!! That little interval there is
really spectacular. Lots of things could be done with that!

This is great, too! I find adding the final A[ to be making the big
chord a bit too dissonant as a "consonant" experience... but
certainly in some contexts it could be used...

I should say right now, that this is giving me a *much* better idea
of how to find these "larger" chords on the lattice!

> Now since we're not quite in JI, we should take advantage of
certain unison vectors, like the 225:224. You see, a lot of intervals

I see what you're saying. So because of the *temperament* we have
certain "equivalencies" here that lead to even *more* "approximate"
just harmonies!

Actually, I really liked this too as a consonance until I added the
final "C." Of course, in certain contexts, that could be useful,
too... but I was basically trying for what I was hoping were
*consonances* in this 8-note chord project

225:224 even helps

Well, that *may* be an ultimate destination, but my *immediate*
objective is to, obviously, find "larger" harmonies in blackjack that
will, quite frankly, take "advantage" of the temperament, as you
illustrate above.

This is really helping A LOT A LOT A LOT!!!!

Well, this is *fantastic* and, like I say, I'm glad I didn't sit
around here any longer trying to "invent the wheel" when all I had to
do is ask a couple of questions! I obviously made some mistakes in
my original experiments and I was getting a little discouraged about
the "big chords..." Clearly, I wasn't thinking about them in the
right way.

My objective in this was to find some really exciting "consonant"
or "semi-consonant" chords that were close to just. It seemed
blackjack should have this kind of resource, and that's why I
purchased the second synth. Clearly, I can see now that it does.

Now, the question comes up about "consonance..." I'm finding, in
first appraisal of some of the harmonies that you list below, that
I'm tempted to leave out a couple of notes here and there to make the
chords more "consonant." I figure I can *always* come up with
dissonant ones... what I was actually looking for were "special"
chords with near-consonances or certain "resonances" that just random
dissonant chords wouldn't have.

I can see, though, that, with what you are providing me, I'm clearly
on the right track at this point. The method using the "slide rule"
seems pretty clear now as well...

Now... without any implicit "criticism" of your extended chords, I
thought I would offer my initial impression... since you asked for my
opinion!

Frankly, in most of the chords, I would leave something out in order
to hear them as the "special consonances" I'm looking for:

CAVEAT:

Of course, *all* these chords could be used in certain contexts, but,
Paul, you asked me for my opinion and, frankly, I would leave a few
notes out on some of these chords.

However, after doing that, I have to admit that these are *exactly*
the kinds of extended chords I was looking for...

Of course, I could hear it all differently tomorrow... (oh, suddenly,
it's *already* tomorrow...)

What if you move it up an octave, above the C>? You _did_ like both
a "seventh" and a "major seventh" in Dave Keenan's first ogdoad . . .
so maybe it's an issue of voicing.

Again, the 15 (here A[) is your problem, so again, try transposing it
up an octave . . .

This is the same chord as above, but now you want to leave out two

[JP:]
Well, actually, as I mentioned above, the octave transpositions of
the blackjack elements really *do* make an incredible difference.
The "voicings" are more distinct than our traditional 12-tET
voicings, so it seems.

I tried transposing some of the pitches I "objected" to the first
time around, and I found them quite acceptable... so there really is
quite a bit to work with here.

Thanks again to Paul and Dave for "blackjack extended harmonic
training." I'm certainly glad I asked about it...

Yes, it worked much better that way. I need bigger hands, though!

That's funny. Sure they're the same... everything transposed up by
a secor. It's remarkable how many transpositions can be done that
way... as evidenced by your chord charts.

If I understand this correctly, though, the "limiting factor" is
actually in making blackjack have "octave equvalency..." otherwise
it would be totally transposable. If I understand this, blackjack is
*not* by it's nature an "octave equivalent" scale...

Besides 64:63, 49:48 and 50:49 are small intervals you can imply with
the small interval in Blackjack. Can you find chords that take
consonant advantage of this, the same way that the chord I gave you
takes consonant advantage of 64:63?

I wouldn't say that, any more than Pythaogean or meantone are not by
nature octave equivalent. I would say instead that to acheive full
transposability, you need to go to a full 72-tET (or 41-tET or even
31-tET if you don't mind the larger errors); but if you're willing to
give up octave equivalency (and thus most inversions of the
interesting chords, though you get some new ones), you can use a non-
octave-equivalent version of Blackjack and have full transposability
by integer numbers of secors.

Hi Paul!

You mean I'm supposed to figure this out?? :)

Actually, I'm composing quite a bit with that those
little "inflections" in Blackjack, so I'm sure I'm "stumbling" into
those chords...

But, how would one figure out something like that *systematically?*

By the way, I *love* my new "big chords!" They've leant a
new "dimension" to my piece, quite literally!!!

Oh sure... I get it. Blackjack comes in various "flavors..." just
like meantone does.... some, with a larger number of
pitches, "circulating" some not ("adjusted")...

I'll get you started here, but I think I should be credited if you're
going to use these in your piece . . . so here goes . . .

Well, the chord with 64:63 in it was 1:3:9:7:21:63, or
1:3:3*3:7:7*3:7*3*3

So something similar with 50:49 would start with 1:5:7:25:35:49, or

1:5:7:5*5:7*7,

and maybe include 35 (5*7), and other notes as well.

Try F< A[ D> C C>.

Try also adding Gb^ (and try different voicings)

If you like that, try also adding Ev. Either way, try to find other
transpositions of this.

Something similar for 48:49 would begin at least with 1:3:7:7*7. You
can find this in many places on the lattice. Try adding other notes,
including 5s.

I'm, quite frankly, a little mystified by what you are doing here.
Is the point in factorizing these to find notes that are directly
linked by the 3, 5, 7 vectors on the lattice??

Hi Paul...

Well, I guess considering its history, that wouldn't be too
surprising. I guess the point I was trying to affirm is that there
are, essentially, more than *one* version of Blackjack, depending
upon how one wants to set it up.... (??)

The absolute pitch needn't correlate with the note names, although it
might. I can't remember. I had to draw them in using the sequencer.
They don't fit on my keyboard, and I'd need three hands to play them
anyway.

Another interesting one with tiny intervals (an octave apart) is
5-1-4^-7-9^-1^-4-7^-3^, but I didn't think of it until I'd recorded the
rest. So there.

Thanks, Graham, for posting these... and just in time for Halloween,
too! These "extended" Blackjack chords are mighty spooky. I have a
section in my new Blackjack piece that is a tad reminiscent of the
Berlioz "March to the Scaffold." Very appropriate for these extended
Blackjack sounds...

Thanks again!

Hi Paul...

Graham has some interesting chords here, obviously based on his "D-
based" notation for Blackjack.

How do I convert that to "C-base" again? It's probably simple, but I
don't want to "mess up."

Thanks!!

Well, if the analogy is to varieties of meantone, then yes, you have
31-tET Blackjack at one extreme, 41-tET Blackjack at another extreme,
and 72-tET Blackjack in the middle.

How are you doing on these, Joseph? Oh, and besides 64:63, 50:49, and
49:48, the small interval in Blackjack can be interpreted as 55:54 --
once you're done with creating 49:48 examples, you can try to find a
chord that shows off the 55:54 . . .

I'm confused. Are we calling the MIRACLE cycles when they go beyond
21 pitches, Blackjack??

No. In analogy to the varieties of meantone, we have 21-out-of-31-tET
Blackjack at one extreme, 21-out-of-41-tET Blackjack at another
extreme, and your current Blackjack tuning in the middle.

Hi Paul...

Well, here is my confusion: I thought that, using the secor
generator, the first time around the cycle was Blackjack, and then
*more* notes were added leading to Canasta, and then another cycle to
41 and, finally 72-tET.

So, in *all* these cycles, the *basic* Blackjack notes are the same.

Is this wrong?

Thanks!

I'm afraid I'm going to need a little more help. I don't want to do
anything wrong!

On a positive note, though, I've been *really* enjoying and using the
new "larger" chords: the "Ramos" ones, in particular contrasted
against Dave Keenan's trumphal "optimal" Blackjack chord.

*That* one REALLY is a gem, particularly in the voicing he figured
out. It's incredibly complex and *resonant* at the same time.

It will be interesting to see if people can identify some of the
chords we have been discussing just by listening to the finished
piece. Probably this piece will be a bit longer than my "usual"
electronic ones, since there seems to really be a lot to explore
here...

And, yes, I will be giving appropriate credit for all the assistance
I've been getting...

Thanks!

Well, if you tune the secor generator to exactly 116 2/3 cents, then
yes, you'll get 72-tET. Otherwise, you won't.*

> So, in *all* these cycles, the *basic* Blackjack notes are the same.

Yes, as long as the precise size of the secor generator is fixed.

*If you tune the secor generator to 117.0732 cents, the cycle will
close at 41-tET. If you tune the secor generator to 116.1290 cents,
the cycle will close at 31-tET.

Well, give the 49:48 a shot. I practically spelled out this case for
you already (and you'll learn more my doing it yourself).

Well, I don't want to cause more confusion, but to be more precise,
using the 116 2/3 cent generator, the first time around the cycle you
get Decimal; the second time, Blackjack; the third time, Canasta; the
fourth time, MIRACLE-41; the fifth time, a 51-tone scale; the sixth
time, a 61- or 62-tone scale; and the seventh time, 72-tET.

🔗Paul Erlich <paul@stretch-music.com>

11/15/2001 2:43:19 PM

By the way, I think the "official" value of the secor is
116.7155940982074 cents, but since you're using 72-tET, you can call
116 2/3 cents a secor and no one will blink.

Hi Paul...

Well, maybe it's time to take a "fun guess..." I'm not entire sure I
know what I'm doing here... John Cage always said things were best
when he didn't know what he was doing, but it's never worked out
quite that way for me...

Let's take the very simple example of:

1:3:7: [7*7]

So I could get simply: C:G:Bb<

Now, I wouldn't know quite what to do except add another connection
of 7, which would be G>

C:G:Bb:G>

But I thought that G>:G was a *larger* interval than 49:48??

Is that it??

This question should really have been posted to

tuning-math@yahoogroups.com

but what the hay.

George Secor defined it as the minimax optimum generator for the 11-
limit mapping we've been calling "MIRACLE". Minimax optimization is
harder than least-squares optimization, an example of which is
illustrated here:

/tuning/topicId_22626.html#22626

There I show that the 9-limit unweighted least-squares optimum is
116.729676636048 cents.

But Secor's minimax value, though harder to derive, is easier to
calculate. Margo posted the formula, but I can't find it now.

Ah yes. It's exactly 1/19th of a just 18/5. That means that if you
use the "official" Secor, 18:5, 9:5, 10:9, and 20:9 will be just.

No -- remember, the smallest interval in Blackjack, the 1/6-tone,
represents the ratios 49:48, 50:49, 55:54, and 64:63.

(1/6-tone is actually a bit _smaller_ than a just 49:48, FWIW.)

> Is that it??

Yup -- now perhaps throw in a few more notes to "fortify" the
harmony -- and look for other instances in the lattice. When you're
done, move on to 55:54 (which might not be as easy to "fortify"
effectively).

Oh sure... it's been a while since I've been over there, anyway. I'm

Of course! Now I remember entirely that process. Although I'm not
getting all the details, I get the general process, which is enough
for now...

Hi Paul!

You know, I keep forgetting that a Blackjack interval actually
approximates several different intervals simultaneously!

Is there a chart anyplace that would show more of this multiple
relationship between just intervals and Blackjack intervals? I think
that would be *very* interesting!

I can see that this process is actually a very important part
of "Blackjack theory..." I'm going to need to practice with more of
this. Right now, I have several different chords I'd like to work
into my piece, but I can see this will be important for "chord
development..."

Thanks again!

Well, maybe . . . For example, the 0/72 interval class represents the
ratios 1:1, 224:225, 385:384, 441:440, 540:539, 1029:1024, 1375:1372,
2401:2400, 3025:3024 . . . The 2/72 interval class represents the
ratios 45:44, 49:48, 50:49, 55:54, 56:55, 64:63, 525:512,
686:675 . . . The 5/72 interval class represents the ratios 21:20,
22:21, 81:77, 135:128, 256:245, 288:275, 360:343, 392:375, 539:512,
605:576, 825:784 . . . Perhaps Gene could complete such a chart with
a clever computer program?

Since there are an infinite number of intervals in each class, you
need to decide what "complete" means. However, you could get a 72-
note 11-limit block (perhaps from an LLL reduced basis), and then
multiply each step by some range of powers of a kernel basis, and
boot out everything above a certain height (defined for instance as
the sum of reduced numerator and denominator.) I wouldn't call that
clever, but it would work; I'm not sure if it would be good for much.

Say, up to four-digit numbers.

Well that's pretty much what I was thinking/doing.

It would be a rare context in which 9:20 would be heard as just.

I understand that what Paul means is that when calculated using the
"official" secor, the approximations to 5:18, 5:9, 9:10, 20:9 will be
exact.

When this 11-limit minimax version of the temperament is played
(asuming essentially harmonic timbres) I expect most people would find
5:9, 6:7 and 8:11 to be just, but while the 5:9 would be as exact as
the instrument could make it, the 6:7 and 8:11 approximations would
have (essentially inaudible) errors of 0.6 c.

In the mannner of fractional comma meantone:

I think someone once called Miracle "meansemitone". I think it might
have been Margo.

The official secor can be considered as a 15:16 widened by 1/19 of
this rather large (~95 cent!) "comma":
2^-75 * 3^21 * 5^18

Not terribly meaningful or useful I'm afraid.

Isn't it interesting, though, to see the just intervals that are
approximated by 72-tET... say out to three or four digits??

Hello Alex!

Well, Paul's considerate request for "lurker-posts" is getting some
response! Well, Paul's not back yet, so I actually get to answer
even *another* question! Whoopie!

Don't worry about being a novice here. I actually occasionally get
complimentary private e-mails from "lurkers" asking me to keep up the
good work asking dumb questions. I fully intend to continue as such.

Books:

1) _On The Sensations of Tone_ by Hermann Helmholtz

2) _Genesis of a Music_ by Harry Partch

3) _The JI Intonation Primer_ by David Doty

Unlike a *lot* of wonderful books on tuning that are presently out of
print, one can *actually get these books!!!* Amazing.

And, you can get them all right here at this link, the Just
Intonation Store:

http://www.dnai.com/~jinetwk/

You should "bug" them, however, about your order by e-mail if you
don't get it right away. I've never had any problem with them in
that department, but some others have. A friendly e-mail (even to
Doty!) will help solve that situation.

After you master everything in these books... should take you at
least a whole weekend...( :) come back here and ask Paul Erlich some
questions.

Now... we live in the Internet age, and books are becoming passe...
(who every said that, don't believe it!) so here are the best
Websites:

1) John Starrett *definitely* on top. Why that (warum?) It contains
everything else!!:

http://www-math.cudenver.edu/~jstarret/microtone.html

2) However, I'll include one other important link. Joe Monzo's
dictionary (also listed on the Starrett but needs to be pointed out)

http://www.ixpres.com/interval/dict/index.htm

Well, now you already have too much to do. After you master all of
this next week, ( :) come back for further discussion!

Please start by asking questions.

Joseph suggested some good books. There are others, but these are the
most easily obtainable, and good place to start (since the "language"
spoken on this list is largely derived from these books).

Also, I hear Juan Roederer's 'The physics and psychophysics of music:
an introduction' is good, but I've never read it. Another good read
(and short) is Siemen Terpstra's 'A Short History of Just Intonation
Tuning Culture', which was published in 1/1 (Journal of the Just
Intonation Network) (Part 1 in vol. 10, no. 1; Part 2 in vol. 10, no.
2). Although this article contains nothing technically related to
tuning, it's a fantastic overview of the various historical
ideologies surrounding just-tuning.

Speaking of ideology, the Partch and Helmholtz are both great books
but in my view are ideologically tainted. Both seem intent on having
sound as an something exclusively physiological, "of the body"
and "of man", whereas many (from Pythagoras to La Monte Young) have
considered sound to be something fundamentally "outside the body"
and "outside man". Interesting to read if one can be aware of this
though.

Hello Alex!

Yes, of course, the books I listed are only a rudimentary
introduction. There are some who speak quite negatively of the
Helmholtz-Partch school, and just intonation recognition in general.
One of the most vocal is composer Brian McLaren (who is a little
eccentric... we call him the "nutty professor"). His book
_Introduction to Microtonality_ is a valuable read, although not
professionally edited. It offers a differing view of a lot of this
from the psychoacoustic perspective. However, it really is for
people already exposed to the field, and not the total newbie, in
*my* opinion. Brian McLaren can be found on the somewhat
appropriately named "Crazy Music" list:

Yes, I've heard of the infamous McLaren. I hear he's been called a
lot worse than that too!

I guess I feel they're neither rudimentary nor such a good place to
start, given their ideological bias. I just wanted to suggest to Alex
that he perhaps start with something more neutral and formulate his
own biases from there.

Okay, you got me! I'm not sure I know of a book that's not
ideologically tainted in some direction. But my intention was to
alert Alex to what I feel are fairly significant underlying
philosophical biases in the Partch and the Helmholtz.

I'm probably not as familiar with the tuning literature as are many
on this list - I read mainly in philosophy and cultural theory - but
I think I _am_ sensitive to how frequently musicians formulate theory
to justify their practice, as well as to how important it is for one
to avoid this style of theory while just beginning to piece the whole
puzzle together. I think any factual book on acoustic science would
be a better place to start. As for specific titles, that's a question
I'll have to throw open: what _is_ the least ideologically-tainted
book on acoustics??

Helmholtz was a scientist, so he approached the matter
scientifically; I think calling that an ideological bias is a
stretch. Partch approached things from quite a different angle, and
if you want to accuse him of bias it seems to me it would be for
those aspects which were *not* scientific, such as an almost
religious attachment to JI. I don't think you've demonstrated any
bias, and I for one have not yet figured out what you are objecting
to.

Hi Alex!

Well, most probably Paul Erlich will chime in (Woodstock chimes?)
with something, but of course there are several list readers who are
actually more interested in practical tunings than they are in the
acoustical basis... or at least my guess is that less than *half* of
the discussions on this forum are about acoustics.

Another problem is that several books on acoustics as related to
tuning... I'm thinking of the Backus, which I own, are substantially
out of date as far as the science goes... or at least that's what
I've been told.

On the overall, one of the sorry facts of the entire alternate tuning
field is the lack of literature *in print* about it. Even great
standards like Murray Barbour's work are out of print. Of course,
not long ago even Partch's _Genesis_ was out of print.

Some of this, I believe, has something to do with the tax code, since
publishers used to keep more older stuff around for a tax credit. I
believe it was Ronald Reagan (for sure bless his heart here) was the
one that eliminated this tax credit, and booksellers no longer keep
older inventory... or something like that...

Please do if you can. It's important to realize what has become known
about the human auditory system since Helmholtz (and therefore since
Partch). However there's virtually nothing about tuning.

There isn't much "neutral" out there, even if that could be defined
in an absolute sense -- the best thing is to expose yourself to as
many ideological biases (inevitable in any individual's work) as
possible and to remain critical of all of them.

As I see it, he had a great ideological bias toward Just Intonation,
and his translator Ellis shows (perhaps going a bit too far) that
most musical cultures did not conform to Helmholtz's assumptions at
all. I think Helmholtz went too far even in equating Western music
with Just Intonation.

I posted a few in my list -- also you may want to delve deeply into
the articles on this website:

http://www.mmk.ei.tum.de/persons/ter.html

Also, the book

Pierce, John R. The Science of Musical Sound. Scientific American
books, New York, 1984, 242 pages.

is very honest -- the author recounts how his own assumptions
(ideological biases?), though based on scientific experiments, were
proved wrong (or sorely incomplete) in the course of his research.

Hi Paul,

I disagree with this. Only Margo writes essays--fifty times more than
anyone else here in fact! I think the technical tuning ideas of
yourself and some others here are often times right up there with the
big boys (and girls), but not the achievements and essays.

For the most part they're just toss offs, shop talk and works in
progress. Not that there's really anything wrong with that, and it
fits the nature of the forum well, but I think your selling the other
folks who've amassed their ideas into books and essays way, way short
(or, conversely, elevating the other folks way too high).

A book like Partch's is a many faceted and artful thing, and it would
really take quite a tuning book to stand shoulder to shoulder with
that. In fact, and I know this will endear me to one and all, I think
Brian McLaren is, with the notable exception of Margo, quite a bit
closer to what you actually said than anybody else you mentioned... by
a long shot!

The historical material and discussion of musical theory would not be
called science back then either, but I think he approached the matter
as a scientist.

He made an instrument in the schismic temperament, and advocated it,
which suggests he was hardly a JI fanatic. He concluded, correctly,
that it sounded in better tune than meantone and in much better tune
than the 12-et.

It is quite unsophisticated compared to the discussions on this list
and especially on tuning-math, however, which I think was Paul's
point.

If it were possible to magically summon into existence a perfectly
objective, scientifically verifiable book full of useful, practical
ideas, theories and their applications regarding tuning and
psychoacoustics, everyone who wanted to believe something different
from its pronouncements would say it was "ideologically tainted".

The above statement is actually a kind of valuable, important-to-
remember tautology.

I think the technical tuning ideas _are_ achievements, easily
comparable to the acheivements of many of the published authors in my
list!

Well, if you look at these folks' webpages (except for Gene), you'll
see material that could easily be expanded into a serious
dissertation. The amount of original material is already sufficient.
Oh, that reminds me, here's another decent reference:

Mandelbaum, M. Joel. Multiple Division of the Octave and the Tonal
Resources of the 19-Tone Equal Temperament. PhD Thesis, University of
Indiana, 1961, 460 pages. University Microfilms, Ann Arbor MI, 1961.

I don't think comma shifts and drifts are preferable to the harmonic
errors of meantone. I think H., not really a musician himself,
focused far too strongly on the acoustical qualities of long-
sustained harmonies at the expense of melodic intonation factors. Of
course, Vicentino's second tuning of 1555 is preferable to both
schismic and meantone, for the type of repertoire that Helmholtz was
considering.

Well, then "relating" instead of "equating". The book is full of this
stuff. Even a primitive pentatonic scale, he insists on presenting as
JI: "1/1 9/8 5/4 3/2 5/3".

Hi Gene,

Technically unsophisticated, mathematically unsophisticated? Perhaps,
but that's just one piece of the presentation--and a rather
pasty-faced piece at that!

Partch's text like his music and his instruments, are works of art.
They've got backbone, depth and color in their cheeks... not to
mention more than a few technical ideas to keep most tuning enthusiast
busy for a while even today.

In fact, most of the tuning theory that I see around here that isn't
strictly acoustics or math, draws mightily from either Partch or
Wilson.

I should have put your name on there too, Dan. You've spend as much
time thinking about/working out tuning ideas as anyone, and though I
tend to be mystified by your terminology and concepts, that doesn't
say anything about the wealth of unique ideas in your posts here, and
the impressive overall philosophical framework that ties them all
together.

Sure, this falls short of a fully presented, readable account;
however, that shortcoming is much less severe in my eyes, than the
shortcomings of a certain prolific author you mentioned, namely that
the vast majority of the ideas presented are misunderstood and
misrepresented, and that the framework in which they are presented
has no coherent philosophy behind it (except, very often, the
philosophy that the author is the greatest mind in history and that
all others are ignorant fools).

Gene and Dan, what I meant by "equal if not better than any"
was "equal to any, if not even better than some". Sorry for the lax
phrasing.

Anything further on this sub-topic should be addressed to

I think this is more in the nature of a limitation than a bias. Not
being a musician both helps and hurts--you can see that at work also
in Euler.

It's the only piece that interests me. I didn't get much out of
Partch's book, as opposed to his music; I could say the same about
Hindemith. Schoenberg I think is more interesting if you ignore the
serialism. I suppose I learned more from Piston's standard textbooks
than from any of them.

A limitation which resulted in a bias, perhaps?

Hi Paul,

Well it's your list and it should reflect the way you feel, but if
there was anyone there who seemed an omission to me, it was Joe Monzo.

He hasn't been around for a while but neither have Hahn or Wolf, and
Joe's done an awful lot for the cause.

As far as Brian goes, I don't agree with his napalm style at all and
have painfully butted heads with him over it in the past. I also find
personal correspondence to sometimes be difficult at best, but still,
he's not without merit, not by a long shot.

His essay, A Brief History of Microtonality in the Twentieth Century
was very inspiring to me. All the obscure microtonalist sounded like
endless exotic locales on a map I didn't even know existed!

It fired up my imagination in many ways and gave me added confidence
when pushing off into uncharted waters. Yes he makes mistakes, but
they never bothered me much... for example, the generalized Golden
scale algorithm and some other related ideas I've come up with were
directly inspired from a bit of McLaren text in A Brief History.

Yet he blotched the Kornerup Golden meantone example he gives... so
obviously there's sometimes more to get from a thing than precise
technical examples, and to McLaren's credit I was able to read right
through that without being any less impressed and inspired. He had
loaded just that brief presentation with more than math and tuning
theory, and in turn it was sturdy enough to absorb such a thing.
That's my take anyway, FWIW.

This is exactly what I was going to tell Gene about Partch! If it
weren't for that Partch book in the library, I may have thought to
this day that trying new tuning systems was not worth my while, that
I'd have to be crazy to spend time and money on them, I wouldn't have
joined this list, etc. etc. And Partch's Tonality Diamond, while it
may be obvious to you, Gene, wasn't obvious to Dave Keenan, so there
has to be some significant originality there.

It would be more accurate to say that I still don't understand the
point of the diamond, as opposed to a lattice. As for lattices, I got
a hint of that from Schoenberg, so thank you Arnold!

Hello Gene!

Schoenberg's _Harmonielehre_ is really a terrible book. (Please
forgive me, Schoenberg fans!) He even makes excuses for it right *in
the book!* It's really amazing.

He obviously *had* to write that thing as part of his teaching
curriculum. _Structural Functions of Harmony_ is, admittedly, quite
a bit better... and it seems that he actually *wanted* to write that
one.

Piston's standard _Harmony_ text is also pretty bad. I *always*
hated that book. Talk about *definitions!* Definition, statement
and *poof*... there's really little thinking in it! I find Allen
Forte's _Tonal Harmony_ book quite superior.

Piston's _Counterpoint_ book is just adequate... pretty good
for "invertible" counterpoint... and, curiously enough, his
_ORCHESTRATION_ book is *outstanding!* I still use it.

Probably, being a composer, he was most take with *that* one of all,
and, for me, anyway, it really shows!

If I recall correctly, Helmholtz really *does* try to pidgeon-hole a
good part of Western Harmony into a just intonational acoustical
mold... even moreso than Heinrich Schenker...

But, still, as a classic compendium, I would think that most students
of tuning would want to read through that book, if even with a few
caveats...

Well that's what I was trying to get at in reply to Alex. If you
eliminated everything that had any bias in it (even if that could be
objectively determined), you'd be left with virtually nothing! Better
by far is to read _everything_ (except for glaring misinformation) --
then at least you'll be in a position to speak the language of
whatever interested parties you may encounter, and then to argue
against the very positions that you feel are biased in a way that
these parties can understand.

Hello, Gene,

But Partch was quite clear to me in his observation that JI just isn't very interesting to a mathmatician, which I ain't...but I wish I could be...Now I'll read the rest of the stuff.

but I think I _am_ sensitive to how frequently musicians formulate
theory to justify their practice, as well as to how important it is
for one to avoid this style of theory while just beginning to piece
the whole puzzle together. I think any factual book on acoustic
science would be a better place to start. As for specific titles,
that's a question I'll have to throw open: what _is_ the least
ideologically-tainted book on acoustics??

Hi Alex!

Well, most probably Paul Erlich will chime in (Woodstock chimes?)
with something, but of course there are several list readers who are
actually more interested in practical tunings than they are in the
acoustical basis... or at least my guess is that less than *half* of
the discussions on this forum are about acoustics.

Another problem is that several books on acoustics as related to
tuning... I'm thinking of the Backus, which I own, are substantially
out of date as far as the science goes... or at least that's what
I've been told.

On the overall, one of the sorry facts of the entire alternate tuning
field is the lack of literature *in print* about it. Even great
standards like Murray Barbour's work are out of print. Of course,
not long ago even Partch's _Genesis_ was out of print.

Some of this, I believe, has something to do with the tax code, since
publishers used to keep more older stuff around for a tax credit. I
believe it was Ronald Reagan (for sure bless his heart here) was the
one that eliminated this tax credit, and booksellers no longer keep
older inventory... or something like that...

Joseph Pehrson

Hey, you guys (a form of address I detest, but...)!

I corresponded with Backus and perused his book many years ago, and found him to be a 12t-ET fascist of the most ardent stripe. I can only hope that things have changed recenty.

Yours,

Pete

It confirms I understood what a Tonality Diamond is, and I like the
shuffling part, as it makes it seem there may be some rhyme or reason
to the order. It doesn't answer my basic question, which is so what?
What good is it? Arranging things so that nearby tones are together
suggests that it might be used as a practial arrangment in
performance, but that's different than saying it leads to any kind of
theoretical insight such as a lattice brings.

I am passing through and thought i would throw in my 4.5 cents.
The tonality Diamond can also be seen as the common tone modulations, in this case a harmonic
hexad which also generates its reciprocal.
Common tone modulations have been useful to quite alot of composers for quite a period of
time.
Now if you also look at http://www.anaphoria.com/lamb.PDF you will notice that the diamond,
being a version of a lambdoma generates super particular ratios between adjacent ratios (in ex.
high to low). Now going all the way back to the greeks, it was noticed that there is something
special about super particular ratios.
Also with Partch's Diamond you have the basis of a 41 tone moment of Symmetry.
As for the actual layout of the diamond you can see quickly which tones ar related by them
occurring in the row the pitch of interest is in.

If you want superparticular ratios in massive amounts you could look
at my stuff about "jacks" on the math list, as well as at the proof
that there are only a finite number in any p-limit. I don't see that
the diamond helps here; the Farey sequence is more to the point.

This does not seem to me to be a good method for producing MOS.

That's more like it. The defect of lattices is that they may be in
more than two dimensions, though you can project them as a la Monzo.

A lattice is generally constructed according to
prime-factorization, whereas the Partch (by way of
Novaro) Tonality Diamond is based on *odd*-factoring.

Partch saw the odd-number series as the one manifesting
the important harmonic information in a multi-tone chord.

Also, as he himself said, the diamond "constitutes
_prima facie_ proof of the at-least-dual identity of
each ratio". (I'm paraphrasing, despite the quotes.)

O-/U-tonal (i.e., harmonic/subharmonic) Dualism is a
very important aspect of Partch's theories, and these
relationships are laid bare on the Diamond.

On the other hand, I tend to agree with you that the
prime-factor lattice conveys the same information in
a simpler (i.e, further reduced) format.

genewardsmith!
The Lambdoma is related to the Farey series as my link points out in the title. Anyway to have
your most closely related notes is a very musical feature.
If all you want is an MOS obviously not the best method. But MOS are only a solution to having
melodic integrity, the diamond solves the other question, harmonic.

I wouldn't call it factoring--it's a product set. There is not of
course unique factorization for odd numbers.

The "dual identity" is completely obvious from the reciprocal map
x |--> 1/x.

It doesn't convey the *same* information, but it conveys a lot more

So Monz or Gene,

Draw us up a prime-factor lattice for the 11-limit diamond and let's
see if it's as intelligible as the diamond layout itself. The lattice
will be four dimensional and will treat ratios of 9's as second-class
citizens. Compare this to the diamond's viewable and playable two
dimensionality and all-odds-are-equal, at a cost of only 7 redundant
vertices.

The lattice will show 9 = 3^2, which is correct; the diamond will
obscure that.

I think this shows a philosophical difference. If something works in

It hardly makes sense to correct the theory when theory, not
practice, was the issue. I wasn't suggesting the diamond wasn't neat,
I was asking what insight it gives.

Gene -- until Wilson, I don't think any musician could draw and
comprehend an 11-limit lattice -- so failing that, Partch's 6-by-6
arrangement shows off as many of the properties of the Diamond as
possible.

Kraig often says MOS when he means CS (which can be thought of as a
circle of modified fifths). 11/10 and 10/9 must be considered
equivalent for this to work.

Wilson's 11-limit lattices are far more enlightening than Monz's --
in Wilson's, the Diamond has a decagonal symmetry, with all the
hexads appearing as regular pentagons (Otonals pointing up, Utonals
pointing down), with their 1 Identity in their centers. But yes, the
6-by-6 arrangement makes this simpler by using only 2 dimensions
(works great for the Diamond pitch set; wouldn't work for others).

Partch's lattice isn't based on factoring at all! Notice how 1/1,
3/3, 5/5, etc, all appear in different places! Meanwhile, Wilson's
lattices _are_ based on odd-factoring.

Right.

In Wilson's lattices, the same note often appears in more than one

Completely obvious to a mathematician, not to a non-mathematical

For the case of the Diamond, a prime-factor lattice might fail to
show "consonances" like 9:5, while Partch's 6-by-6 arrangement
manages to convey _all_ the important information, as far as I can
see. However, once you start adding more notes, the flat arragement
is toast.

Kraig, Gene understands the coolness of the tonality diamond as a
pitch set -- in fact he came up with the same concept independently --
he just thinks that depicting it on a lattice tells you more than
depicting it Partch's way.

Yes, a lattice is a perfect way of viewing pitch sets if one is

Stand corrected, since more scales I tend to work with are CS than MOS, yes i do this.
In reference below i would just like to add that Wilson will generate more than one lattice for
any system when he feels it shows properties that are apparent in others. As one can see in

Exactly! Even if one is skeptical of this "independent musical
existence", one must admit that Wilson's lattices make dyads which
are ratios of 9 look like "consonances" just like ratios of 7 and
ratios of 11 (as they should be), while a true prime lattice will
tend to obscure the consonance of the ratios of 9.

We shouldn't equate the words "theory" or "theoretical"
with "impractical" and treat theory and practice as mutually
exclusive or as having an intrinsically adversarial relationship.
This perception of these terms has obscured communications here.

Gene said the lattice promotes "theoretical insight", which is always
good. You can't play either the diamond or the lattice diagrams, so
the apparent "practicality" of the pitch order is only a conditioned
perception based on musical practice that creates the comfortable
illusion of understanding and little more.

Theoretical insight translates to everyday language as greater depth
of comprehension and consequently more ability to handle larger
amounts of interacting information with greater ease and
simplicity...and THAT has GREAT practical value. Theories that don't
work to unify and simplify to a comparitively few elements the
comprehensive range of specific possibilities under consideration
don't count. They're just bad theories. So people should stop dumping
on theory as impractical simply because some theories are bad. I
still eat apples, even though rotten apples do indeed exist.

Bob replies:
Yes, I half expected someone to answer with that. It's obviously a
possibility, but has little to do with the point of my reply. I was
referring to the hard copy or screen dislplay of the diagrams, which
are not playable, and whose purpose is manifestly simply to
communicate information in as effective a manner as possible. This
might be aided by playability although that is not essential to
comprehension of the information displayed.

The ONE and ONLY purpose of theory is to elucidate and facilitate
practice. It is essential to practicality and not antithetical to it.
So I would love to see an end to this "practical" posturing that puts
down the vital role of theory as if "theoretical" were an antonym
for "practical". This latter perception is a very popular idea based
on a complete misunderstanding of both the nature and purpose of
theory.

Yes, undoubtedly theory must be born out by practice, and in this
regard, practical utility is the ultimate criterion for the value of
any theory and is therefore king. Even so, without the unifying power
of coherent, comprehensive theory, practice becomes lame.

The theoretical insight to which Gene refers often leads to renewed
creativity and important new discoveries. One of the good things
about this list is that theories get proposed and theories get
challenged. Also theories that have long been proposed get aired and
challenged (and illuminated for better or worse). Hopefully only the
good ones will survive.

Antithetical, no. Essential? Hubris maximus. Please, someone talk
about the theoretical background that Howlin Wolf absorbed before he
developed his eminently 'practical' blues renditions. Including
microtones.

More on this later - it's been an interesting thread, especially
since the subject line asked for reading about "microtonal music",
the author said he had been involved in "microtonal music" for some
time, and in addition to the 'usual suspect' books (which garnered
their traditional support and raspberries) was treated to books on
acoustics and other extrapolated topics.

But I'm grabbing my one day off with my teeth, so everyone have a
great Thursday... in theory.

Somewhere, at some point, there was a free plug-in *from* Adobe *for*

I'll do a search and see if it's still available, and if not check to

Quite right. That's pretty much what I meant to say, but you seem to
think you're disagreeing with me. I was pulling Gene up on his (roughly
paraphrased) "it works in practice but not in theory" which I consider to
be bogus. I'm sure he didn't really intend it to come out like that, but
his clarification is still somewhat ambiguous.

I'm with you on the first sentence. But ISTM that alot of practical
musicians can get by fine with very little theory. Let's not give
ourselves delusions of grandeur.

Yes, I expect that's what he was thinking. But in the interests of good
theory, it is a mistake to ignore the practical benefits of a diamond
layout. It's a theoretical construct that has practical advantages. So
it must be good theory.

Erv Wilson's CPS diagrams are the theoretical advance that builds on the
diamond layout's advantages. I don't think I could have made that step,
but Wilson did and it looks like so much numerology until you consider the
practical benefits. Once you do understand it, all the theoretical
treatises about the impracticality of just intonation suddenly begin to
resemble a steaming pile of bovine ordure. Perhaps there's another
breakthrough around the corner, and we won't be able to find it if we
can't see beyond those regular lattices.

And to drag this thread back on topic, the reason Partch stands as a
towering figure of 20th Century music theory is that he was the one who
showed that high-limit JI could be of practical, musical benefit. Even if
he didn't make much use of the JI harmonies, that's the path he took and
to understand it you could try to read his book.

I don't think there's any "essential reading" about microtonality. You
could stay on this list and learn from the rest of us who are trying make
sense of it. But mostly you have to learn for yourself by tuning up some
scales and, if necessary, working out some ideas on a spreadsheet. Not
enough people have done this and made great music as a result for us to
have a set of key ideas that can be written up and taught to newcomers.
Almost by definition, anything well understood and appreciated isn't
"microtonal". So many good ideas are sitting in journals, and there are
so many different approaches you'll have to work out for yourself what you
need to know.

Still, Partch and Darreg are good places to start. Then Wilson and
Sethares.

Okay, I'll get off my soap box now ...

You understand the math of all this far, far better

I don't recall saying that. I also don't recall learning anything of
*theoretical* significance from Partch; this is unlike the case with

It don't think a diamond layout can be called a theoretical

I'd be more impressed with this argument but for the fact that I knew
about these before I even read Partch--from lattices. And lattices I
got, more or less, from Schoenberg. That is not to say that reading
Partch is not a reasonable route to the same place, but I think it
would be a terrible idea to go only as far as the diamond in your
understanding and then stop.

So he asks about _essential_ reading about "microtonal music", and
you choose to send him to Math and Music, with the above breakdown of
subjects. I downloaded that .pdf the first time you posted it and
spent an hour or so 'thumbing' through it.

Are we so poor in this area, that we have no book to point to that
uses *music* as the starting point, and brings in the other subjects
as necessary parts of the scheme? Is microtonal music going to be
always doomed to start it's life with a calculator, an oscilliscope,
and an anechoic chamber?

[You know me well enough to imagine my tongue-in-cheek, but the basic
thrust is there: not everyone who wants to find an alternative to the
12tET prison is going to approach it from the science side - some
will come from the music side, no? We need resources for them!]

And, frankly, I wish I *could* recommend a 'one' book.

Yep, that lame diamond concept, limiting as it is, surely must have
been the reason that Partch was only able to create 50 years worth of
unique works, wide-ranging in style and manner, including an entire
orchestra of instruments well-sprung from that paltry source. Some

There's an idea. I think I'll add an undergraduate text on linear
algebra and abstract algebra to the list, and maybe the first part of
Jacobson's "Basic Algebra" to make sure you didn't miss anything
basic. Then some elementary number theory, such as Hardy and Wright
or Niven and Zuckerman, something on diophantine approximation, and
something which at least defines valuations.

I'm not sure if I'm kidding or not; I'll think about it. :)

Partch never really took full advantage of his own ideas, it seems to
me. As for the diamond, I'm afraid when I read it it struck me that
Partch had gotten half-way to understanding things, and then got
stuck. So sue me.

What you said is "Arranging things so that nearby tones are together
suggests that it might be used as a practical arrangement in
performance, but that's different than saying it leads to any kind of
theoretical insight such as a lattice brings." And also "It hardly makes
sense to correct the theory when theory, not practice, was the issue."

Gene:

You can write a diamond on paper, and there are general rules for
constructing it, so it must be theoretical.

You knew about CPS scales or the way Wilson draws them? Did you get as
far as D'Alessandro, and do you have an alternative that works with
Canasta? I knew about lattices before I read Schoenberg, if that means
anything.

Of course, if something's of theoretical interest you don't stop with it.
Now I'm thinking about the reordered diamond, it's the same principle as
my 9-limit lattice <http://x31eq.com/lattice.htm#9limit> where

Partch's ear took advantage of things within the diamond that most here only find by number
crunching. BTW since you have so little interest in the diamond just what do you have to have
musicians to play upon.

I have no idea if you like or are interested in Partchs 'end
product'. I don't care, because musical tastes are very personal. But
your comment is, "it seems to me", further documentation of the gap
between those who would endlessly 'experiment' and those that find
resources to make something, and then make it. You completely gloss
over an entire body of work to focus on the small aspect of what
could have been. One way of looking at the world, I suppose, but
pretty limiting.

He wasn't a theorist, he was a composer, and he went as far as he
*needed* to - he found materials to base his composition on, and used
them. That he found even that much concept, essentially working alone
with little precident, is pretty striking. But the fact that he
didn't end up endlessly refining and refocusing the underlying fabric
of the intonation system he chose is meaningless in light of the
compositional accomplishments.

Except to some mathematicians and theorists, apparantly.

Graham replied:
I'm with you on the first sentence. But ISTM that alot of practical

ourselves delusions of grandeur.

Bob answers:
Why "delusions of grandeur"? The musicians you refer to are standing
on the shouders of those whose theoretical work laid the practical
foundation and generated the fundamental musical resources for
everything those musicians do. These musical resources, whether they
understand them theoretically or not, are what they manipulate to
produce their music.

That this manipulation is intuitive detracts nothing from the
value of the theoretical foundations upon which their musical
resources are based. Without these pre-existent resources and no
theoretical understanding of their own, they could do little. Don't
forget that the understanding of generations of musicians is embodied
in many of our instruments, most especially those well-adapted to
microtonal performance.

Finally, to say that practice without theory becomes lame (or
perhapes better, blind) DOES NOT HAVE TO IMPLY that any particular
musician must understand theory in order to practice or even to
astound. So why take this as if it were the only possible
interpretation? On the contrary, theory is by nature global and
practice, local. So it runs counter to the very nature of theoretical
discussion to interpret such a statement about theoretical
understanding as necessarily applying to individual practitioners.

I'm presuming that someone coming to this list is already familiar
with the basics of music. Dave Benson's article traces the
development of Western music, with plenty of listening requirements
cited. It then directs you to recordings of Harry Partch, Wendy
Carlos, and other microtonal greats, while discussing a bit about
their theories; hence I would say that it uses music as a primary
reference around which everything else is geared.

D'Alessandro has lower symmetry than any of the CPS scales it is
constructed from -- in fact D'Alessandro is simply the [3 5 7 9 11]
Euler genus.

Paul!
Euler failed to recognize 1 as an element causing him to fail to see the Hexany, Dekany and
Eikosany, which are the more interesting aspects of this set. The structural symmetry, hence the
musical meaning is different. It is quite possible to construct a Full CPS out of a set without 1
of course. D'Alessandro fits well on a 31-tone Bosanquet Keyboard. If one wanted the full
symmetrical set, you add a harmonic hexad on the square of the other 5 elements plus their
reciprocals pitches.

Wilson has hunted high and low for a predecessor of Combination product sets so if you or any
of these others can refer us to a mathematician that did this before, outside of themselves seeing
this obvious while in high school we would be truly interested.

Fairly big apologies if I missed that in the big .pdf file I was
scanning through. I must admit that my eyes glazed over a bit during
a lot of the math presentations, but the book leads the title
with "Math" so it certainly didn't bother me at all...

That's funny, because I see quite a bit of stuff on the list that
doesn't have anything to do with music. And I don't even remotely
mean that as an insult.

Well, you've got me, pal. I don't know how Wilson draws them, I know
nothing of D'Alessandro, and I don't see what any of it has to do
with Canasta. Of course any comma induces an equivalency on a
lattice, which includes the commas of miracle.

Did you think them up from something else, or get it somewhere else?
I got lattices from Schoenberg rather indirectly, passing through a
stage of the dual tiling of chords, which was related to Schoenberg's
tonal regions. It would be interesting to know how this business
evolved, and from where.

Sorry, but this is nonsense. The diamond was put forward as a

weather Partch overlooked the implication of the diamond it seems might be more than an opinion.
Listen i don't use the diamond, but if i had been brought up in a culture that had it for its

D'Alessandro is the 3.5.7.9.11 Euler genus with some notes added to fill a
meantone keyboard designed for 31 notes plus some duplicates. It means the
keyboard functions melodically like meantone, but it's all JI. There are two
problems with converting it to Canasta. Firstly, pairs like 3 and 11.5.7
can't both be represented because 385:384 is tempered out. Secondly, it
overspills the 41 note MOS instead of the 31 note one.

The genus was chosen because it contains all the CPSes. There may be a
similar Miracle-unique scale which also has a lot of CPS subsets.

You need so many Miracle notes because factors of 27 come up as 3.9. In
meantone or schismic that's good, because it encourages modulation by fifths
and fifths are cheap. In Miracle, they're 6 Secors, so it pays to be more
frugal with them. As 9 is already 3.3 you can probably get by without 3.9 as
well, but I don't have a modifiied CPS that takes account of this.

If these problems could be worked around, it would lead to a just tuning of a
Miracle keyboard.

I was working with elementary music theory. Triads and keys. I drew a
triangular and square lattice to make the relationships easier. All part of
fumbling towards the realisation that a 5-limit scale has to be founded on
two basic intervals, but there's no uniquely privileged pair that does the
job. At that time, I didn't see how to diagram the 7-limit in two
dimensions, so switched to numbers for everything.

If you take a major third and stretch it a bit, you get 9:7. But 5:4 and 9:7
aren't particularly close on the usual 7-limit lattice. The same with 7:6
and 6:5. So the 9-limit lattice gives you four different triads where the
third gets higher as the middle note gets higher up the lattice. 9-limit
chords are no more complex than on the 7-limit lattice, but you get some of
the melodic advantages of a generalized keyboard.

Then it is your expectations, and not the work(s) in question, that
are askew. You see the Diamond, and you assume that every avenue
should have been explored; he looked at (and heard) the Diamond, and
he used it for musical expression.

Eloquently put. Does all your dialogue run along these lines?

> The diamond was put forward as a theoretical innovation by Partch
> of some importance; I did not bring it up.

At the time, it was; it still has some staying power, as other
composers are still utilizing it's resources. But you have chosen to
place an importance on it that was not his, looking at the glass as
half-full ("not fully realized"); others find that same glass
brimming with opportunity.

Not to mention his reasoning behind writing "Genesis of a Music",
where the Tonality Diamond rears it's ugly head:

"It is addressed to those who are searching for more than
intellectual openings into the mysteries of music and intonation. I
have written it for those with a musically creative attitude: (1) for
composers; (2) for those who expect to compose; (3) for anyone, even
without a knowldege of ordinary music theory, who has this creative
attitude."

The book, and the theories, have flaws, biases, and areas that have
been superceded in the years since. But it also stands that it is
about a lot more than theory, which, unfortunately, is how many
approach it.

I am not mad. I save that for important moments, and avoid it when
possible.

> Does this make sense to you? It doesn't to me.

You look at the theory first, the work second, and find it lacking
(somehow, somewhere). You find his 'fault' in not fulfilling the
promise of the diamond, and I say you've got it bass-ackwards. *That*
doesn't make sense to me, but I see it a lot.

Neither does describing as "garbage" and "well-written ignorance" a
book you haven't even read. Sorry, I expect a little more...

I agree with you that they are the more interesting aspects of this
set, and that Euler failed to recognize them. But it's not because he
failed to recognize 1. Instead, Euler Geni and CPS scales are very
different in their symmetries, whether 1 is included or not.

I'd like to understand better what you mean here (by "square", for
example), and I'm sure you are correct, but if you're going to end up
accusing me of "intellectual imperialism", maybe you better keep it
to yourself.

Wilson took a combinatorial approach, and I took a geometric one.
There is a wide area of overlap, but not an identity, and I think a
discussion and comparison of the two approaches might be interesting.
I was going to launch into some theory when you told me that I was
talking about hexanies. I thought I'd better go read up on hexanies
first, but having done that I think both points of view are valid and
could both benefit by being tied together.

I'm not totally clear on what you're asking there, but if
it's concerning the history of tonal lattices, I can offer
this: the big pre-Tuning-List names are Euler, Riemann,
Tanaka, Fokker, and Wilson.

The 5-limit triangular lattice, under the name of Riemann's
"Tonnetz", was employed quite a bit in theoretical literature
(especially German) of the 1800s.

You assumed someone would know about music. I seem to recall that
Pierre Lamouthe (sp?) claimed he was not involved in music in the
least. Other people have professed the love of numbers all by

I came up with lattices through the tetrahedral-octahedral lattice
independently on my own. I wasn't optimistic about being able to
visualize higher dimensions. When John Chalmers showed me Wilson's
lattices for the 9-, 11-, 13- . . . limits, I was impressed -- yes, a
little bit of symmetry had to be broken, but not much!

Well, isn't it the product set of the 11-limit hexad with its
inverse? Doesn't the diamond layout show this most clearly? And what
of your lattice -- if you don't include an axis for 9, won't you be
obscuring the diamond's symmetry?

Partch clearly presented the diamond as a generalization -- specific
examples include the 5-limit lattice, the 11-limit lattice, and the
13-limit lattice. Similarly, CPSs have specific examples. How is one
more abstract than the other?

I qualifed it by saying *if* the review was on target in suggesting
that those who promoted systems other than 12-et were the Bad Guys,
then it "sounded" like garbage. But you are in danger of
contradicting yourself here--if not supporting 12-et is evil, what
are we to make of Partch, for whom even the likes of 53-et was not
good enough? You knew the man--what do you think he would have
thought of this attitude?

Graham (and Gene),

Are you familiar with the fact that the Tenney lattice has a built-in
pitch axis? What about Canright's 2-d lattices which also have a
pitch axis built in? If we're interested in seeing pitch height on
our lattices, these types of approaches would seem preferable . . .

His approach was geometric as well, and also resulted in an
octahedron. I too thought I had come up with it first, as the
octahedron in the tetrahedral-octahedral lattice, but John Chalmers
informed me of Wilson's precedence. Something I'd be mildly
interested to know (and perhaps Kraig would too) is if anyone before
Wilson realized the correspondence between larger CPSs and higher-
dimensional symmetrical figures, analogous to the octahedron.

Don't forget the "Duodenarium" in Helmholtz-Ellis; Barbour's
lattices, which did have the triangular arragement; and Donald Hall's
nice hexagonal tuning lattices (also the triangular arrangement but
allowing for the display of the error in each interval).

Well, OK, so let's say someone came to this list not knowing much
about music. What do you find lacking in Dave Benson's article/book
for the needs of such an individual, and what would you suggest as a
means to fill that gap?

You mean this Euler genus? I wouldn't consider that to have the full
symmmetry of the Eikosany or Diamond -- it has lower symmetry. Or do
you mean that this set would _contain_ some highly-symmetrical set as
a subset?

Interesting . . . would you like to give some examples? (again, no

publication, though personally, I always spill the beans)

He actually even diagrammed and plotted out a diamond to the 17-
limit, but it existed on paper only. The materials were given to Ben
Johnston in the late 40's or early 50's, I believe...

I'll hazard there have been a lot that passed through, looked for
musical guidance, and spun around on their heels. I don't necessarily
think that's bad, in that sometimes the extra effort is rewarded. But
we're back to the old music<>math debate, which is tired. For both
sides...

Remember: we are allowed to pull apart all manner of diagrams,
lattices, spreadsheets, theories, historical treatises -- but we
can't talk about the strengths and weaknesses of composers and
compositions presented here. It Just Doesn't Work. Way too much
crying, which is why other lists have formed.

Maybe you missed something in one of my posts to you: I tried to say
that I'll give the book another glance/read, but (1) I *can't*
recommend a better suggestion right now, and (2) I think there is a
Critical Need for a book on the subject of alternate tunings and
microtonal music that comes from the music first, and works in the
tunings bit by bit.

As Dan so perfectly explained, and politely too, those who are very
well-inclined with the math end of our world very often do *not* see
how much of a barrier it can be to many musicians, and how intensely
valuable it would be to find a text that didn't simply present the
material, but presented it *well* - to the 'layman'.

I'd be the first name on the pre-order list.

This is a reasonable request, but it can only be taken so far.
Creation and evaluation of tuning systems is partly a matter of art,
but it really is more a sort of engineering problem. Like so many
engineering problems, math comes into the picture. The problem is
that artists usually don't think in this way, and probably some
people winced when they read the word "engineering". Sometimes they
do, and it is not an accident that perspective was invented by one
artist-engineer, Bruneschelli, and developed by another, Leonardo. I
think a Leonardo point of view would help anyone trying to explore
this mostly uncharted territory. Fainting in coils is not painting in
oils.

You really think Dave Benson's course falls short in this respect? It
looks to me like the kind of course you would take if you hated math,
were really bad at it, but needed one course with math content to
fulfill your college requirements. Plus it manages to give a complete
novice to the subject enough information to understand virtually
everything on this list, and much more. Just skip the sections that
don't interest you or look too hard -- each section is self-contained.

I said exactly the same thing to Joseph Pehrson a few months ago, in
response to some talk about "science" and tuning. It's not science, I
replied, but it's very often engineering, and hence can get quite
mathematical.

That's right -- they pick up the 12-tET guitar and keyboard and
proceed to make music on it. They don't appreciate that the
mathematicians/engineers who came up with the tuning system they're
using had to solve "music's greatest riddle"!

I look forward to it, but note that we're talking about far more than
just 12-fold symmetry. For example, in the 5-limit, the [3 5] Euler
genus has four axes of reflectional symmetry and four angles of
rotational symmetry, while the 5-limit diamond has six axes of
reflectional symmetry and six angles of rotational symmetry. In the
11-limit these numbers are in the hundreds.

You mean in the tetrahedral-octahedral lattice? He popularized it,

earlier. I'd guess that the ancients were well aware of it -- I

It's not a matter of guilt or innocence <g>, but it would sure make

The second and third sentences from the *Introduction*:

"The prerequisites for this course consist of differential and
integral calculus, and either calculus of several variables or
ordinary differential equations, as well as an elementary knowledge
of music notation. Parts of the notes require a little more
mathematical background."

Guilty again, Paul. Look, I'm not a mathematical illiterate,
especially since my second degree (in software engineering) included
a fair amount of catching up on math subjects I had earnestly avoided
(including 'slaying the dragon', which was how we referred to the
Calculus classes...). And while people might be willing to bash me
for bringing up this Hatfield vs. the McCoys subject again, don't say
I don't try: I still have the .pdfs of the book, but I went back and
downloaded not only the Postscript files but the Ghostscript
environment and previewer as well, all to try and *read* the thing
better.

When I have some time.

But if this dog still has mainly mathematical fleas on it, I'm coming
back here and demand that you quit your job and write a proper book
on the subject, coming *from* the musical angle that you claim as
your main residence.

Going to bed,
Jon

I've always thought of Tenney as a 3-dimensional square lattice person. But,
sure enough, the lattice in CMJ11.1 is similar to my 9-limit one. David
Canright's lattices do their own thing, but aren't optimized to show
particular chords. The disadvantage of those approaches is that they can't
be shown in ASCII. Another difference with mine is that they only order
pitch height horizontally, whereas I look at the vertical as well.

I don't get it. Pitch is a 1-dimensional quantity, so mapping it to
one axis is perfect. What do you mean, then?

It's standard math department boiler plate which basically means the

Surprised? That means you recommended it without being familiar
enough? <g> Hey, all chiding aside, I *did* end up staying awake
until about 3:00 am, and I would recommend people - no, musicians
wanting to get a grip on tuning when being less than stellar
mathematicians - can very much go to chapters 4, 5, and 6 (I think
those were the ones). I'm going to hunt up a Postscript printer to
print them out (there is an especially funny cartoon to post to this
list, BTW...).

But honestly, take a look at Chaps 1, 2, or 3. Take them around to a
bevy of practicing musicians, and watch what happens. THAT is what I
meant by needing a guide that starts out with music as the FIRST
principle understanding, and goes the other direction. The world
waits...

I believe, if I remember correctly, that there were a *couple* of

music. I believe one of them was particularly interested in the

This is a very, very interesting topic, and I'm not much of an
authoritative source on it... :)

However... it's really interesting, since we have Gene who is
unimpressed with the intellectual rigor of Partch's theorizing and
Paul Erlich who was so "bowled over" by Partch's book that it got him
started in alternate tuning. Paul's not really all *that* stupid, is
he?? :)

My point is that (hopefully I'll not be too simplistic) art has a way
of communicating that is *not necessarily* the path of the greatest
intellectual rigor.

I suppose it differs from science and mathematics in this respect.
Frequently pieces of music that are created strictly by rules of
science and math can be boring or repetitive. (Please don't ask me to
name the names of the composers... :) )

However, other less "rigorous" methods, such as those of Partch or,
maybe, Varese, create products that engage and inspire deeply.

So, in short, _Genesis of a Music_ is an *art* book, not a rigorous
science or math text.

I guess that's pretty obvious... but it seems to be slightly
forgotten momentarily in this debate... or so it seems to me..

Pitch is only a sensation parametred by log (frequency).

The few I read about perception phenomenology (Merleau-Ponty) convinced me that sense investment is possible only by mean of differentiation ; and the unconscious part tends to be organized in systems.

What keeps trace of sense with pitches is the field of intervals : differences of pitch height. This field is not, perceptively, only linear. There exist a planar topological invariance in the auditive field : a complete width order combined with an harmonic preorder which are correlable, strictly by perception, in the begining portion of the Stern-Brocot tree. The Tenny's distance is simply a complete order idealization of that, but useful in context of lattice having few low primes.

The harmonic dimension is not an algebraic dimension. Differences of sonance are not composable. The formal algebraic structures of musical modes concern only width differences, but there exist an harmonic order in the space of well-formed tonal structures. I would say that time tends to respect the simplest among them.

There is a problem with the harmonic entropy approach until date. Rather than to refine a categorical perception model, it tends to reduce all at a sensitive perception model. Without showing how its particular differences are integrated to a contextualized perception, I think it brings nothing to the essential questions.

So it is. So what? Pierre, you're jumping in here with all this, some
of which I agree with, but do you even understand the context of the
discussion in which this statement came up? And to what degree that
context actually _supports_, rather than contradicts, many of the
claims you're making?

Again, I do not appreciate having statements of mine taken out of
context like this. If you'd like to participate in our discussion,
Pierre, I would like nothing better. But what you are doing here is
very intellectually dishonest -- you go away for a long time, come
back and pick up on a tag line you'd like to run with, and use it as
a launching point for a criticism that seems (superficially) to paint
your intellectual superiority.

I have a suggestion for you -- cut it out, and help us understand
your axiom system over at tuning-math. Gene (if I may speak for him)
and I are all ears. Gene has been creating all kinds of interesting
structures based on the way I think about tuning -- no doubt he can
develop much of interest from your way of thinking about things too.
You and I are blessed to have such a fine mathematician involved with
interest in our speculations!

You have pitch ordered in two dimensions on a guitar fretboard, so why not
a lattice? In fact, as you have a 22-equal guitar you can get close to
that lattice by tuning the open strings F-A-C-E-G-B with 5-limit thirds.

Joseph! I left out 243:242 here! How could I!

Thanks, Paul! Obviously nobody else noticed it... or at least they
didn't comment!

In terms of the unison vectors we've discussed most frequently, it's

243/242 = (2401/2400) * (225/224) * (225/224) * (384/385) * (384/385)

This is probably why no one found or mentioned it before!

What do you mean? See
/tuning/topicId_26488.html#26511
and I expect Graham Breed mentioned it in relation to Blackjack long
before that, since it is the neutral third comma, the difference
between a 2:3 perfect fifth and a stack of two 9:11 neutral thirds.

What? Yes. Here: </tuning/topicId_21957.html#21985>.
225:224 is the interval between 16:15 and 15:14, and 385:384 is what stops
a 6:5 minor third and an 8:7 supermajor second making an 11:8 sub fourth.
Approximate them all away, and you get Miracle temperament.

2401:2400 is only important if you want a 7-prime limit system. It means
two 5:4 major thirds and a 3:2 perfect fifth approximate the same as a
string of 7:4 subminor sevenths.

For some other notable equivalences, an 8:7 supermajor second followed by
a 15:14 semitone is sharp of an 11:9 neutral third by 540:539. If you
used a 16:15 semitone instead, you'd need to temper out 385:384 again.
The 441:440 unison vector makes an 8:7 supermajor second plus a 10:9 major
second the same as 14:11 supermajor third.

The best way of showing all these relationships is a lattice or
generalised keyboard, not a list of numbers.

Well, they commented _preemptively_. And Graham is right, these
things are best understood on the lattice, rather than numerically.
