Krzysztof kuhy Rudnicki d5b3f2cff3 music_theory: music theory from first principles, as code you can hear ... New subproject porting Luke Haas's "Music Theory for Programmers" section by section into typed Python: pitch (MIDI <-> Hz), tuning (harmonic series, the Pythagorean comma, brute-forced "why twelve"), scales as step arrays with modes as rotations, chords stacked in thirds with Roman numerals and the V7 -> I resolution, named progressions, a numpy synth (waveforms, ADSR, low-pass), a bar-exact sequencer, and a seeded Recipe -> WAV composer. `degrade` is the same piece ruined by a 0..1 amount, so an ending can be the opening destroyed on the same seed; filtering runs LAST because filtering first measured brighter than the clean render. 17 demos (`python -m music_theory demo all`) each print the article's numbers -- the comma is 1.013643, the tempered fifth is 0.113 % flat, twelve is the first acceptable division -- and the FFT of the render, so the claims are tested rather than asserted. 157 tests, 100 % branch coverage, ruff ALL, mypy strict, pylint 10. Consumed next by roadside-assistance for its three world-state beds.
