Hello all!

Happy to see the list working again. Here I'm going to repeat my obviously

lost message of December 13 for a third time:

"Ever heard of a scale that divides the double octave into 47 steps? It is

non-octave, naturally, and its equal-tempered version accomodates 7- and

13-limit intervals exceptionally well. I came across it when playing a little

with "Pythagorean" scale approaches. For those interested I put it up on the

Net:

My best wishes for the New Year to you all!

This is simply every other step of 47 tET. I've played with a number

of these scales which are multiple octaves divided by an odd number of

steps. One of my favorites is three octaves divided by 19, or every

third step of 19 tET.

Hello Heinz,

My apology. Actually, I did see the article on your web site shortly

after the first time your message was posted. Very interesting!

I wasn't thinking as clearly the next time I saw your article and my

mind immediately went to equal divisions of multiple octaves -

something that I had been pondering recently.
