Ooops, I've figured out the [q,r] nomenclature now.

It means diatonic with q of one size and r of
another (I hope it doesn't care about ordering of
sizes).

So, in my post...

...which is a [5,4] scale.

Meanwhile, I went back to look at the [7,2] we were
discussing last week. The [n,2] scales (n != 3, 5...)
seem to give my program problems, there are too many local
minima for it to provide a good guide.

Personally, I liked his approach of using sargam instead of solfege,
although I'm more used to the latter (I sometimes did the exercises using
do-re-mi, or no syllable at all where it felt more comfortable). It seemed
to help greatly with the internalization process, which seems to be the main
point of this book. I'm no more singer than many on this list, an octave
plus a few notes on a good day, but singing the tones against a guitar drone
and *feeling* the resonance has been very beneficial, I feel like I get some
aspects of JI in a way that I never did before! To me it was helpful to
learn to construct the just scale from the ground up, so to speak.

I haven't gone through the 12ET section yet, I mostly bought the book for
the first part, but it looks interesting. In the same way hat many of us
will use an x-tET to approximate JI, he obviously advocates the change in
perception that a musician could have when playing in 12 after gaining more
understanding of JI.

Have a great Harry Partch Centennial everyone! See you later, I'm going

or perhaps just bang on a rock and sing and howl at the sun and stars...

Jay Williams here,
Well, I'll be hornswoggled! NPR's Sunday Week End Edition actually
announced Partsch's anniversary and played a sound clip of him. In the same
breath or breaths they mentioned that on this date in l967 "White Rabbit"
and "A Whiter Shade of Pale" were released. A day full of auspicion?

From: John Chalmers <JHCHALMERS@UCSD.EDU>
Subject: Re: Digest Number 1440

Greg: It's an Euler genus all right, just another projection, one that
causes some vertices to coincide in 2-D space. I was inspired to program
it because I came across a book on the Fourth Dimension in Art
("Foufield: Computers, Art & the 4th Dimension) by Tony Robbin, an
artist who tries to depict 4-D objects in his own work. Back in the
1970, I met him in Houston and had some correspondence with him, but had
lost contact.

In his book, he showed part of a diagram of a central projection of a
7-D hypercube and I immediately saw that it was based on the
centered-heptagon lattice that I had programmed earlier (based on Erv
Wilson's ideas). So, I merely had to insert a table of the notes
corresponding to the hypercube or Euler Genus.

As far as I can tell, hypercubes only in spaces with odd numbers of
dimensions can be projected meaningfully this way. In the cases of
even-dimensioned spaces, I have had to use some sort of rectilinear lattice.

Since I already had the programs written, I decided to compute (or write
routines to do so) the notes for all the hypercubes from 2 to 9
dimensions and plot them. Most look very comprehensible and attractive,
except, perhaps, the 9-D hc which is basically a black lace doily with a
nearly solid center due to the low resolution of TrueBASIC and my Mac.
However, the overly of red dots where the notes are looks quite good.

The hypercubes in even-numbered spaces are less attractive -- the 2, and
4 D cases are fine-- a square and a projected tesseract, but 6 and 8 are
blobby, though if I have time to adjust the angles and lengths of the
underlying lattices, they may improve somewhat.

Oh, it's all Secor's, so what did "The briefest on notes from Erv Wilson-"
mean?

There isn't much text, so indeed we don't know how he found it. But what
he found is definitely Miracle. He mentions transpositional invariance,
the consistency with 31-, 41- and 72-equal. Also:

"If the above keyboard is tuned so that each key plays 116.69 cents
different in pitch from the one beside it, a temperament will result in
which none of the 29 primary ratios within the 11-limit will be more than
about 3.32 cents false. With 43 tones per octave, this permits 21
complete otonalities and 21 complete utonalities!"

And there's a 5-limit square lattice showing some Miracle approximations.
He uses this for his notation: nominals are Pythagorean and the
accidentals move you to different rows. No mention of Blackjack, so that
might be a new idea.

As is 46-tET . . . Dave Keenan and I have been thinking about a
subset of 46-tET for fretting the Shrutar, since the vanishing of the
diaschisma (2048:2025) seems to be implied in the Indian system.

Yes -- you must have missed my post a couple of days ago where I
suggested "linear temperament" to you in this context (it was the
post immediately following the one where I suggested "Forms of

Yes there is, Monz. You must have forgotten that only a few short
weeks ago, we went over the "relative error theorem", which shows
that simply adding the cardinalities of two ETs will result in an ET
which has small errors for a given interval if the original ETs have
small errors for that interval.

Yup, I missed that or forgot it. Well... uh... "a few short weeks
ago" we were also going over the amazing "new" MIRACLE temperaments,
the demise of the practicaltonality list in vivid brilliant flames,
your having been banned from it, the birthpangs of several new lists,
impersonations of McLaren, etc. etc., and I was gushing all over
the new-found applicability of 72-EDO to Starr Labs instruments.
So yes, I forgot it...

Thanks to Herman, Marc Jones, and you for setting me straight.

It's actually very simple. The _relative_ (that is, in units of the
ET in question) signed errors simply add when you "add" ETs. We went
over this a few weeks ago, and I called it the "relative error
theorem".

It depends how you construct the lattice. Erv Wilson often gives
composite odd numbers their own distinct axes, which can sometimes
make the musical relationships clearer.

Because the commas are defined as the difference between different
pitches in JI, _not_ as the difference between pitches in JI and
pitches in 12-tET.

Jo,

It's only my memory so I wouldn't hang too much on that. So
I hope I'm not putting words into Erv's mouth here. I
couldn't check this at the time as my copy of his handout is
in a file at work.

Yeah. Me too!! Incidentally, several of my students find
your website a fantastic source of information particularly
on lattices. And I too will use it, along with
anaphoria.com, as I attempt to get my head around his
theories.

This was a _very- strange reaction, Michael. I have no idea how any
of it makes sense as a response to what Kraig wrote. Is there some
conversation from another list or off-list that would clarify this

Hi Robert!

You should post these scales to the tuning-math list -- I wonder if
any or all of them came out of Graham's search . . . I envision a big
book with all of these scales (as well as diatonic, MIRACLE, etc.),
deriving each of them from a colorful JI lattice with certain unison
vectors being tempered out, as we've been discussing . . .
