tonalitytools.ChordClass

class abjad.tools.tonalitytools.ChordClass.ChordClass.ChordClass(*args, **kwargs)

New in version 2.0.

Abjad model of tonal chords like G 7, G 6/5, G half-diminished 6/5, etc.

Note that notions like G 7 represent an entire class of chords because there are many different spacings and registrations of a G 7 chord.
