musicaiz.harmony.Chord

class musicaiz.harmony.Chord(chord: Optional[str] = None)

__init__(chord: Optional[str] = None)

The Chord object can be initialized with a valid chord name or not. The logic behind this is having methods for generating and analyzing data.

Initialization:

• By initializing this class with a chord name, the use of this class’ methods

  will be to generate data with the chord information.

• By initializing this class with no input arguments, the use of this class’ methods

  is more related to analize data (predict chords…).

Raises

ValueError

if input chord name is invalid.
