This piece is my fourth one with with 13ED2 (Equal Division of ratio 2:1 into 13 steps of 92.308 cents each) tuning system, after 13 Miles, Fast And Furious 13 and SazDul 13.
It is based on a heptatonic subset of 13ED2 (3, 1, 2, 1, 3, 1, 2). I created it thinking of 2 large tetrachords (553.846 cents each) divided by a small interval (92.308 cents).

It is a free improvisation featuring sounds from Omnisphere (saz and dulcimer), Alchemy (pad) and Ultrabeat (percussions).
All instrumental tracks (percussions included) derive from the original improvisation played with a saz sound.
I overdubbed a vocal track in my “tribal” style that I subsequently edited with Melodyne Editor. Because Melodyne only reads Scala files, LMSO translated my heptatonic subset of 13ED2 into a dodecatonic subset of 26ED2 (3, 3, 1, 1, 4, 1, 1, 3, 3, 1, 1, 4).

In order to record the vocal track on the spur of the moment I set up my Apogee One as USB microphone and in a matter of seconds I was ready to go!
