I fear there is no corpus...

If you're more of the JI type, try the just tuning I mentioned below. Oooooh, and I just
tried a mode of 31 equal (every other note plus one little skip) and it is quite nifty!

Hmmm. My experience was with banging on a keyboard with a bright-sounding
piano patch. My setup prefers systems with average step size close to 12 because it
stretches samples horribly at the extremes. To my delight I could get a lovely
harmonic 11th chord (my fascination with which I owe to Prent).

Here lies a "hyperimprovisation" (i.e. sped up) that is far from perfect, although I hope
to flesh it out into a formal piece some time. Most of the fun harmony comes from
playing parallel intervals; these are the most sensible progressions I can make with a
normal keyboard so far.

Hey, there's a lovely sonority at 1:15-1:17 in the mp3. Maybe I ought have
another look at 15-tet !!!

It has a frenetic restlessness as well as a psychedelic 'Alice in Wonderland'
feel that I kind of like, too.

Ara (my partner in microtonal crime) was playing some rich, thick
chord progressions in 15-equal (far from mere triads) and it sounded
just fabulous. I'll see if I can get him to record some of that stuff
next time . . .

"Now, Jacob: Where'd you get the 15-tet piano sound in "3.3.mp3" ???"

Emu Proteus/1 XR. 'Tain't software, sorry to say.

"15 keeps you moving fast, since most of the intervals are pretty far
from JI, and sitting on them can be "painful".

And I do have a tendency to keep on movin', I'll admit it. That would explain my
delight in 15...

If 12-et is red meat, what is 15? Pork liver?
