to keenan : RE: [tuning] Re: [MMM] music for pelog and about the previous work(hi fi stereo , ....)

Hi keenan

As I don't know anything about odd-numbered pitches (can you tell me
more about it), but 18-ed(1215.) is non-octavic equal divisions , so it
is subset of 9-ed(1215.) and not 9-edo.

One thing to ask is that in scala if we consider non-octave degree ,what
about the repetition of scale after and before the main , are divisions
different From the main scale?

Since this doesn't contain any odd-numbered pitches of 18-edo, it's
really a subset of 9-edo, right? But it sounds like you used some of
the odd-numbered pitches in your piece.

The piece sure doesn't sound much like gamelan, but it's eerie and
enchanting.

Well, 1215 cents is close enough to be an octave for me.

What I meant was, if you say you're using 18 equal divisions of
something, but you only use the even-numbered ones, then you're really
using only 9 equal divisions, because 0/18 = 0/9, 2/18 = 1/9, 4/18 =
2/9...

You might as well say there 27 or 36 or 9000 equal divisions. It
doesn't matter if you don't use them.

I don't know much about Scala, but I can't see why it wouldn't use the
same intervals in every repetition.
