Data

Introduction

This module provide a collection of models available in the library for different types of musical data. It provides predefined chord patterns that can be used to generate chords based on a root note.

Chords Model

ChordModel is a class for handling chord models in musical data.

class musicnpy.data.ChordModel

Bases: object

Database of chords intervals (semitones from root)

Example:

>>> print(ChordModel.maj)
>>> [0, 4, 7]

aug = [0, 4, 8]

aug7 = [0, 4, 8, 10]

aug_maj7 = [0, 4, 8, 11]

dim = [0, 3, 6]

dim7 = [0, 3, 6, 9]

dom7 = [0, 4, 7, 10]

dom9 = [0, 4, 7, 10, 14]

dom_b9 = [0, 4, 7, 10, 13]

french_aug6 = [0, 4, 6, 10]

german_aug6 = [0, 4, 7, 10]

half_dim7 = [0, 3, 6, 10]

italian_aug6 = [0, 4, 10]

maj = [0, 4, 7]

maj6 = [0, 4, 7, 9]

maj7 = [0, 4, 7, 11]

maj9 = [0, 4, 7, 11, 14]

min = [0, 3, 7]

min6 = [0, 3, 7, 9]

min7 = [0, 3, 7, 10]

min9 = [0, 3, 7, 10, 14]

min_maj7 = [0, 3, 7, 11]

neapolitan = [0, 4, 8]

prometheus = [0, 6, 10, 16, 21]

quartal = [0, 5, 10, 15]

quintal = [0, 7, 14, 21]

sus2 = [0, 2, 7]

sus4 = [0, 5, 7]

tristan = [0, 3, 6, 10]

Scales Model

ScaleModel is a class for handling scale models in musical data. It provides predefined scale patterns that can be used to generate scales based on a root note. It includes the chords of the scale as well, which are derived from the intervals of the scale.

class musicnpy.data.ScaleModel

Bases: object

Database of scales with intervals and diatonic harmonization.

Example:

>>> print(ScaleModel.maj["intervals"])
>>> [0, 2, 4, 5, 7, 9, 11]
>>> print(ScaleModel.maj["harmo"])
>>> [ChordModel.maj, ChordModel.min, ...]
