So what is TOP Pelogic again??

Could somebody run that by me in a way that I could possibly
understand??

Thanks!

It's the tuning used for both "Mysterious Mush" (where it also
determines the inharmonic partials of the timbre) and its "Just"
complement (a misnomer, since the tuning was not Just Intonation, but
the timbres there were periodic, so that the tuning results in much
worse beating).

TOP Pelogic is a tuning system with an interval of repetition of
1206.55 cents, and a generator of 522.52 (or 685.03 = 1206.55 -
522.52) cents. The interval of repetition is supposed to approximate
the 2:1 ratio, the generator is supposed to approximate 4:3 (or 3:2
if you use the larger inversion), and a chain of *four* generators
(mod the interval of repetition), 327.02 cents, is supposed to
approximate 6:5 (unlike meantone where four generators gets you to
5:4).

Since you wanted them included in Monz's dictionary, I assume you
understand horagrams, right?

Here are the horagrams for TOP Meantone and TOP Miracle, both of
which would probably make a lot of sense to you:

/tuning/files/miracle.gif

In the same form, here's TOP Pelogic:

Is this helping?

***Oh! So this is the tunign with the slightly "stretched" octaves
and slightly "stretched" generator... Interesting. Well, it would
make sense than that if the timbre was not correspondingly stretched
it would beat more as a harmonic timbre. Thanks for helping to
clarify this; it's very interesting...

But what does the term "Pelogic" mean?? I guess it means it's
somewhat related to the tuning system Pelog... but how??

Thanks!

Yes.

The generator is an extremely stretched fourth or *compressed* fifth.

And compressed in some places (the interval between the second and
third partials, being a fifth, is very compressed for example)

Some older theorists, as well as Easley Blackwood in his 23-equal
etude, have interpreted the Pelog tuning system and scale as the 7-
and 5-note MOSs arising from an extremely-stretched-fourth (or very-
compressed-fifth) generator. If you look at or listen to the
corresponding rings in the pelogic horagram, the resemblance to at
least some local variants of Pelog should be apparent.

But really, the interest in this temperament lies in the fact that,
like meantone, it "eats" a simple 5-limit interval. As you know,
meantone "eats" 81;80. Similarly, pelogic "eats" 135;128. It seems
that Gene and I have found two different ways of re-mapping intervals
so that 81;80 turns into 135;128, allowing a meantone piece to be
unambiguously converted into a pelogic piece. My method, which I
first described quite a while ago, is the easiest -- the meantone
generator is simply altered by a fraction of a semitone to become the
pelogic generator. The fascinating result is that all major triads
become (rough) minor triads, all minor triads become (rough) major
triads, and the diatonic scale turns into an approximation of the
Pelog tuning system -- but the notes remain in the same order. Gene's
method is more "warped" and alters the order of the notes, but major
triads get mapped to (rough) second-inversion major triads,
etc. . . . I asked Gene to elaborate but he has yet to respond.

Erv Wilson's notation and keyboard mapping on page 10 of
http://www.anaphoria.com/xen3a.PDF
is appropriate to pelogic and any similar system.

Herman Miller and others have created a lot of text and music around
these ideas; you seem to have been away from the list when this was
going on, though . . .

Best,

Maybe "pelogic" should really be called "mavila"?

See the first page of this Erv Wilson article:

http://www.anaphoria.com/meantone-mavila.PDF

Wilson seems to be using the equation

+4 = "5"

to express how meantone generators are chained to arrive at an
approximation of the 5th harmonic. His equation for mavila is

-3 = "5"

which would seem to correspond exactly, by analogy, to how we've
defined "pelogic".

The MOSs Wilson lists seem to support this hypothesis, agreeing as
they do with the rings of my horagrams until one is quite far from
the center. One wouldn't expect exact agreement since, as we know,
Wilson's "meta" paradigm is different from the TOP paradigm.

Unfortunately Wilson is far from explicit here. Kraig, are you
around? Can you shed some light? Also -- Herman take note.

This seems to have been anticipated by Erv Wilson on page 6 of

http://www.anaphoria.com/meantone-mavila.PDF

What does the word "enantiodromia" mean? Apparently, the process when
a thing is replaced by its opposite.

http://phrontistery.50megs.com/e.html
http://home.mn.rr.com/wwftd/def.htm#enantiodromia

Was Wilson referring to the fact that major triads are converted into
minor triads here and vice versa? Or small steps into large steps and
vice versa? Or both?

***So, essentially with TOP Pelogic, you've created a system where 5-
limit intervals are just (??) and the chromatic semitone is
maintained (??) Isn't that what 135;128 is all about??

And when do you use the ; rather than the : ? (just as a matter of
definitions...)

No, their errors are larger, quite a bit larger than in meantone, so
certainly not just.

> maintained (??)

The chromatic semitone actually changes direction, so F# is *lower*
than F if you notate the chain of generators in the traditional way.

> Isn't that what 135;128 is all about??

What I'm saying is that, just as 81;80 *vanishes* in meantone, and
225;224, 1029;1024, and 2401;2400 all *vanish* in miracle, similarly
135;128 *vanishes* in this "pelogic" (or perhaps better, "mavila")
system. See below.

> And when do you use the ; rather than the : ? (just as a matter of
> definitions...)

We've occasionally used ";" instead of ":" when the tuning system is
tempered rather than just, to emphasize that the frequency ratio is
not simply the ratio of the two numbers, but rather a particular
temperament's representation of the interval. It's to be formed the
same way, through a chain of consonances, but the consonances are
tempered rather than just.

In JI, one can form 81:80 by going up three fifths and down a major
sixth plus an octave. In meantone, this same chain of consonances
lands you at the unison (i.e., exactly where you started). In JI, one
can form 135:128 by going up three fifths plus a major third and
going down two octaves. In pelogic/mavila, this same chain of
consonances lands you at the unison.

Well, it's been *much* more recent than 1999.

The TOP version of the temperament, in theory, minimizes the
maximum 'damage' any interval suffers from being mistuned relative to
JI. So it might be just the ticket if your hope is to best preserve
the traditional consonances, while exploiting the unusual topology
the temperament offers you.

In addition to all the cool things about Mavila (formerly 'Pelogic')
that I've posted about here recently, the TOP version (if you use,
say, the 9-note ring) has some really narrow intervals -- 31 cents!
In fact, if you notate 'conventionally', a *sharp* becomes 31 cents
*down*, and a *flat* becomes 31 cents *up*. Too subtle for some,
perhaps, but I know you've learned to love such tiny intervals,
Joseph ;)!

The temperament is one of my favorite resources and I know Kraig
likes it too, having used Erv Wilson's tuning of it -- Meta-Mavila --
on at least one of his CDs . . .

Tragic.
