After come inspiration from Rick's posts I have decided to try my luck at converting my PHI scale to 34TET (I tried the more mathematically accurate 36TET, but found 34TET best avoided the problem Chris noted of over-beating PHI-taves by tempering them to about 1.625 instead of the usual 1.618034 while still maintaining the same general feel of 36TET).

So have a listen and I'd appreciate it if you let me know...does the above 8-tone scale (with all tones droning as a huge chord) sound consonant to you and, if not, which parts/notes stick out as sour?

Nothing particularly sticks out, but it does NOT sound
consonant to me, at all. Sounds quite dissonant, though not
in an uninteresting way.

Hi Mike,

I honestly don't know what's going on here. Is it a scale because the notes sound like they're jumping around a bit? And why 34TET? The numbers do not have the many advantages of 36 like being divisible by 2,3,4,6,9 etc, while the "phi" range doesn't seem very close at all. Why not try taking some of your more successful note-limited scales, see if they fit into 36 or near enough and imply a pattern, and go on from there?

ONTH, I quite liked the two pieces 12th root of PHI and Silver2 which are starting to resemble actual musical compositions. You know if you want to divide PHI up into equal symmetries besides 5 which is already in 36TET, you can always multiply the denominator 36 in the index by the desired number: third division 2^(25/(3x36=108)) = 1.17404 etc. Of course these imply new TET's 108 etc...For the 12th root of PHI, the problem is that 12 X 36 = 432 is too small to be of much use. Obviously you chose notes out of this set of 12 intervals for your composition with larger intervals.
