Swift library for music theory, currently focused on chords/harmony.
Tonic answers musical questions, such as:
What's the note for this pitch in this key?
Note(pitch: Pitch(midiNoteNumber), key: .Bb)
What's the name of a chord?
Chord(notes: notes).description
What chords are in this key?
Key.Cm.chords
What chords in this key contain this note?
Key.C.chords.filter { $0.noteClasses.contains(.C) }
What notes do these keys have in common?
Key.C.noteSet.intersection(Key.Cm.noteSet)
What notes don't these keys have in common?
Key.C.noteSet.symmetricDifference(Key.Cm.noteSet)
These questions are all tested in our unit tests explicitly.
