Musical scales 24tET: to my knowledge they're all seven note; that I propose, however, has eight notes.

Hi Hans Straub.
1) I know already that there are other 24tET musical scales . To my knowledge they're all seven notes musical scales.
The quarter-tone scale (24tET) that I propose, however, has eight notes.
Do you know of the exsistence of other 8 notes musical scales?
I designed the quarter-tone scale because managing a music system that is generated by a 8 notes musical scale is less difficult than a system based on a 7 notes scale. I figured that the coefficient of difficulty (measured on the number of musical alterations) drops from 76% to 57%.
2) when I decided to call H the eighth note, I knew already that the same letter is used by German musicians instead of B. Remains true, however, that in the vast majority of the Western world the predominant notation is by far A_B_C_D_E_F_G. I simply aligned myself with this reality
3) I agree: the best way to spread a new music system is to hear the music already composed. But to your question if there is already this music in movement, the answer is double-face.
A) No, with my scale, since I'm not a composer.

B) Since it's a 24tET scale, which is more than 150 years old there are plenty of compositions: Alaleona, Haba, Wyschnegradskji, Carrillo, Partch, Darreg, Blackwood, Halevy, Bartok, Ives, Penderecki, Xenakis, Scelsi, schnebel's music and others.

Thanks for your attention. Bye.

I have not used 24TET much - but, e.g., the 24tet page on our xenharmonic wiki (http://xenharmonic.wikispaces.com/24edo) lists several 8-note scales in 24TET, especially approximations of arabic scales. I added your scale and a link to your page there, BTW.

Since I am not an expert in 24TET, I don't know how your scale fits in with the existing literature and composers, Haba, Blackwood and all the others. Maybe someone else here knows more?

Giancarlo, there are many 24EDO scales halfway down this page:

Hi Giancarlo,

We microtonalists deal with scales of every number of notes,
from 5 per octave to hundreds per octave.

For one example of 8-note scale and notation, see:
http://groups.google.com/group/microtools/web/diatonic-notations

If you want to share your scale with microtonalists, the
standard format is the Scala scale format:
http://www.huygens-fokker.org/scala/scl_format.html

Since they are plain text, Scala files can be posted to the
list in your message body.

I would be interested to learn more about how you compute
your coefficient of difficulty.

Of course there are 8-note scales in conventional music
theory also, such as the famous "octatonic" scale,
0-2-3-5-6-8-9-11 (in 12-ET degrees). What is its coefficient
of difficulty?
