mutwo

Mutwo is a flexible, modular, event based framework for composing music or other time-based arts in Python. It aims to help composers to build musical structures in a meaningful way and translate those structures to different third party objects (e.g. midi files, csound scores, musical notation with Lilypond via abjad). The general design philosophy stresses out the independence and freedom of the user with the help of generic data structures and an easily extensible and tweakable software design.

The following example generates a short midi file:

from mutwo import core_events
from mutwo import music_events
from mutwo import midi_converters
simple_melody = core_events.Consecution(
    [
        music_events.NoteLike(pitch_name, duration=duration, volume="mf")
        for pitch_name, duration in (
            ("c", 0.75),
            ("a", 0.25),
            ("g", 1 / 6),
            ("es", 1 / 12),
        )
    ]
)
event_to_midi_file = midi_converters.EventToMidiFile()
event_to_midi_file.convert(simple_melody, "my_simple_melody.mid")

Making Western notation via abjad of the same melody:

from mutwo import abjad_converters
import abjad
abjad_voice_converter = abjad_converters.ConsecutionToAbjadVoice()
abjad_voice = abjad_voice_converter.convert(simple_melody)
abjad_score = abjad.Score([abjad.Staff([abjad_voice])])
abjad.show(abjad_score)

Modular design

Starting from version 0.43.0 mutwo uses a modular design. Only basic functionality is provided by the mutwo core package.

Added internal functionality

  • mutwo.core: Base package for mutwo ecosystem
  • mutwo.music: Add music parameters (pitch, volume, ...) and a SimpleEvent based class to represent a Note/Chord/Rest (NoteLike)
  • mutwo.common: Algorithmic generation of data to be used for artistic works
  • mutwo.timeline: Place events on a time line by start and end times.

Added conversion methods

Writing new plugins is simple, its basic structure can be understood at the mutwo.example repo.
