chord-progressions's Introduction

Chord progressions

Usage

See the Makefile for available actions.

Docs

The documentation uses Material for MkDocs to build a static site from Markdown files. Use mkdocs serve to start a live preview server of the site that automatically rebuilds upon saving. Use mkdocs build to build the site.

TODO

Analysis

[feature] get key for progression
[feature] get functional names for chords given key
[feature] extend interval class vectors to "polychord content" vectors

I/O

[feature] add from_audio and from_midi constructors to Progression class
[maintainability] use a singular method of counting in extract_harman.py
- get_segment_label uses counter
- get_segment_pc_weights uses defaultdict
- MinimalSegment.get_pitch_class_weights uses list.count()
[performance] extract.midi_harman.segment_and_label() gets really slow for many consecutive segments. test that a maximum of six segment evaluations occur per note

Generation

[feature] VAE solver
[feature] use variable chord durations
[feature] consider lower and upper structures in select_voicing
[feature] add the possibility of repeated notes in different octaves

Misc

[feature] Host docs site
[feature] Generalize noteNumberToFrequency to use any periodic tuning (see https://github.com/soul-lang/SOUL/pull/26/files)
[feature] implement is_partial_circular_match, chord_contained_in_type, and get_possible_types_of_chord
[maintainability] mk pitch_class refer to "C" and call 0 pitch_class_ix
[maintainability] pass midi note numbers everywhere as "notes" and include note names as "noteNames"
[maintainability] test the merging of chord types
