music-dsl
Pure music-theory domain library: notes, intervals, scale degrees, chord
qualities, scales, and chord encoding. Zero runtime dependencies. This is the
Python reference implementation; TypeScript (@tonalis/music-dsl on npm) and
Rust (tonalis-music-dsl on crates.io) ports conform to the same spec and a shared
433-case conformance suite plus a seeded three-way differential fuzzer.
music-dsl is the theory core underneath tonalis,
the format-agnostic lead-sheet DSL, and is fully usable on its own.
Install
pip install tonalis-music-dsl
Use
from music_dsl import Key, Notes, Scales
key = Key(Notes.Bb, Scales.Major)
# deeper theory lives in submodules
from music_dsl.domain.chords.chord import Chord
chord = Chord("C7") # raises InvalidChordStringException on bad input
print(chord.encoding) # canonical numeric chord encoding
The import name is music_dsl (underscore); the distribution name is
tonalis-music-dsl.
