An algorithmic approach to music generation using the rules of harmonic motion

Installation

Requires Python 2.7 and mingus

Setup

1. virtualenv venv
2. source venv/bin/activate
3. pip install mingus
4. Run with python src/musgen.py.

You should now see two new new MIDI files at src/ - a comp track and a melody track. Drop these into a DAW and give them a listen.

Available Parameters

progressionLength = 12 // Number of chords
key = Key.G // Key of progression
meter = (4,4) // The measure meter
scale = Scale.Major // Major or Minor
firstScalechord = Chord.I // The first scale degree

Rules of Harmonic Motion

TODO

• Command-line arguments for parameters and output directory
• Output audio files in addition to MIDI
• Ouput sheet music
• More harmonic variety
• More rhythmic variety
