Otousan no Ao

Описание: This is a rather odd piece in 13 EDO. It uses the Mavila scale (2L5s) as well as a 5 note sub scale which is almost 2L3s, but not quite. The name comes from the fact that this scale sounds very similar to the Japanese pentatonic scale known as "In." The word "otousan" is a polite Japanese word for "father" and "ao" is a Japanese color word covering blue and green. The use of the word for father is because of the fact that 13 EDO is an example of so-called "father" temperament.

13 EDO does not have fifths, but it has a decent sub-minor third, good ninths, and an exceptionally good 11th harmonic (11/8). This means that conventional harmony doesn't work. The 2L5s scale of 13 EDO is generated by the 11th harmonic, and the harmony in this piece emphasizes the 11th harmonic as well as the ninths and the minor third.

I used a Buchla-style process for most of the instruments in the song, with the exception of the pad and the hi-hat/snare. Buchla synths use a "complex oscillator" which consists of 2 oscillators where one "master" oscillator is modulated by the other. The output of this modulated oscillator is then passed into a wave shaper, where the sound can be made even more complex. Buchla, or "West Coast" synthesis starts with simple sounds and builds them into complex ones, as opposed to Moog or "East Coast" synthesis which uses the more familiar subtractive technique.

DAW was SunVox and graphic was made with pixilang.

P.S.: I had this sitting on my computer while it was in the repair shop, so that's why I uploaded it so soon after the last one.
