The tuning systems span equal temperament, just intonation, and shruti (22 microtonal divisions per octave). Reference pitches range from standard 440 Hz to 432 Hz. Keys range from G major to Eb minor. Tempos from 40 BPM ambient drone to 140 BPM trap.
**Every sound is generated from code.** Each track is a `.py` file — a Python script that defines instruments, notes, rhythms, effects, and structure using [pytheory](https://github.com/kennethreitz/pytheory). There are no samples, no DAW, no audio files checked in. The music is the source code. Run it and it renders to audio in real time — sine waves, saw waves, FM synthesis, physical modeling of sitars and mellotrons and singing bowls, all computed from math and played through your speakers.
