- Add pytest as dev dependency in pyproject.toml
- Fix sawtooth_wave: numpy.linspace requires int for num parameter
- Fix Scale.degree() lookup by name ("tonic", "dominant") was broken
- Add tests for: Tone.from_tuple, from_index, _index, error paths,
multi-octave arithmetic, descending chromatic walk, all pitch frequencies,
Pythagorean temperament, all scale degrees by Roman numeral and name,
Scale repr/slice/degrees mismatch, TonedScale repr/get/with-Tone-object,
D/F/A/E/B major/minor scales, D Dorian, G Mixolydian, octave boundary
crossing, all mode intervals including Phrygian/Aeolian/Locrian/Ionian,
chord intervals/beat_pulse/empty chord, Chord/Fretboard fingering errors,
all NamedChord qualities (m6/m9/maj9/9), fix_fingering, flat-to-sharp
conversion, charts total count, charts_for_fretboard, all wave generators,
wave output types, Synth with real pitches, circle of fifths/fourths,
relative minor equivalence, enharmonic equivalence in scales, I-IV-V
progression integration test

PyTheory: Music Theory for Humans
This (work in progress) library attempts to make exploring music theory approachable to humans.
True Scale -> Pitch Evaluation
>>> from pytheory import TonedScale
>>> c_minor = TonedScale(tonic='C4')['minor']
>>> c_minor
<Scale I=C4 II=D4 III=Eb4 IV=F4 V=G4 VI=Ab4 VII=Bb5 VIII=C5>
>>> c_minor[0].pitch()
523.251130601197
>>> c_minor["I"].pitch(symbolic=True)
440*2**(1/4)
>>> c_minor["tonic"].pitch(temperament='pythagorean', symbolic=True)
14080/27
Audibly play a note (or chord)
>>> from pytheory import play
play(c_minor[0], t=1_000)
Chord Fingerings for Custom Tunings
>>> from pytheory import Tone, Fretboard, CHARTS
>>> tones = (
... Tone.from_string("F2"),
... Tone.from_string("C3"),
... Tone.from_string("G3"),
... Tone.from_string("D4"),
... Tone.from_string("A5"),
... Tone.from_string("E5")
... )
>>> fretboard = Fretboard(tones=tones)
>>>
>>> c_chord = CHARTS['western']["C"]
>>> print(c_chord.fingering(fretboard=fretboard))
(0, 0, 0, 3, 3, 3)
It can also generate charts for all known chords for any instrument (accuracy to be determined!).
