A more complete attempt to make quasiperiodic music. I'm trying to make suitable intro music to use on my youtube channel https://www.youtube.com/channel/UCfR8iwcgwxXBQSpwbl-EGMw

Intro Music

Inspired by Steve Reich's Piano Phase, I wanted to see what a similar piece would sound like using the Bohlen Pierce scale. I used the Groove settings in LSDJ to make a melody in 7/4 time where one channel gets 1/32 of a note behind on each repetition.

Gameboy Phase I

Like GB Phase I, this is inspired by Reich's Piano Phase. I wanted to hear what it would sound like to use all 13 Bohlen-Pierce notes so I made this version. I tried to arrange the notes so that they would have good relationships.

Since it goes through all the tones, it's a tone row.

Algorithmically generated rhythm and melody. The quasiperiodic rhythm was selected randomly, and then the quasiperiodic scale was hand-tuned to a slightly tempered 7/2 and 3/2 and an exact 9/7.

Random Quasiperiodic Rhythm

Algorithmically generated rhythm and melody. The 1D quasiperiodic pattern is based on the golden ratio (with long, medium and short intervals of ~1.618, 1.0, and 0.618). The melody is generated essentially the same way as the rhythm, and the intervals for the melody are balanced to not drift too far up or down, but other than that the melody's intervals don't make too much sense.
