Gon-Tanz.mp3
Piano piece in 19EDO. The title is a pun - more precise, a spoonerism of "Ganzton" (whole-tone), which refers, of course, to the scale (derived from a series of 9 whole-tones). The point that interested me here was the fact that whole-tone scales in 19edo do not have such a fearful symmetry as in 12edo, and I wondered whether a whole-tone piece in 19edo would have less of that notorious "amorphous" or "rootless" character that is so typical for many 12edo whole-tone pieces.

C64 Random Impression 1.mp3
All sounds were programmed on a Commodore 64. This machine, when programmed in the right way, can be turned into a surprising musical instrument. The piece consists of random-generated melodies without rhythm, without structure, without development. Boring to death if you insist on listening "actively", but not that bad as background. Based on a whole-tone scale, which creates slightly impressionist effects.

C64 Random Impression 2.mp3
Same algorithm as "C64 Random, Impression 1", with slightly different sounds.

C64_Atmosphere.ogg
Statistic sound experiment inspired by Iannis Xenakis: pitches sliding up and down like atoms in a gas.(Unfortunately, there was an artithmetic overflow in the software that caused all pitches to end in a low grumble - for the same reason, the whole thing ends after 50 seconds...) Maybe not exactly music, but in any case an example for the surprising sound facilities of the Commodore 64. In OGG vorbis format.

asimchomsaia.mp3
The first successful result of my experiments in the field of alternative tunings. It uses 5-tone equal temperament, i.e. one octave is divided into 5 equal steps. Additionally, it is in 5/8 measure, which gives a far-going symmetry between pitch and time component, enabling me to use various slightly crazy mathematical techniques, such as arbitrary two-dimensional transformations applied in the way that classical composers use inversions and retrogrades.

Those C64 "random impressions" are even more fun if you *play* them actively, multiple copies together and overlapping ... Grin - I think I wanna be a DJ when I grow up! Cool

Hey, Hans, just had to stop by to say I really love this piece!  It is indeed one of the more successful microtonal pieces I've heard (and I've heard way too many ...)
 
So, Hans, tell me, what were the 2D transforms you used?  (In matrix notation would be fine.) 
 
After all, just the usual old inversion and retrograde, along with temporal diminution and augmentation, makes for a limited palette of transformations, and may become boring for some listeners.  But it's not at all obvious to me what other transformations you could expect listeners to pick up on!  Any thoughts on that?
 
Best,
Yahya
