double_jig_gen - Double Jig Folk Music Generation

Build Status Code Coverage

My entry for the AI Music Generation Challenge 2020 at The 2020 Joint Conference on AI Music Creativity https://boblsturm.github.io/aimusic2020/

The model generates a specific sort of folk music called a double jig which exhibits the following musical features:

  • disclaimer: I don't know a thing about folk music!
  • in 6/8 time
  • melody has (loosely) two groups of quavers (8th notes) per bar
  • phrases may end in a dotted quaver (three 8th notes)
  • ornaments like substituting the second quaver in a triplet for two semiquavers
  • probably more things - people disagree: https://thesession.org/discussions/4231

Setup

System

brew install wget

Python environment

conda create -y -n dj-gen python=3.8
conda activate dj-gen
# pip install .
pip install -e ".[dev]"
# TODO: auto install correct pytorch for given platform
pip install torch torchvision
# pip install torch==1.6.0+cu101 torchvision==0.7.0+cu101 \
#     -f https://download.pytorch.org/whl/torch_stable.html

Configure Music21

Then run the following:

from music21 import configure
configure.run()

Also, make sure you open MuseScore and accept the query box first, else you'll get errors in the notebook e.g.

dlopen error : dlopen(/usr/local/lib/libjack.0.dylib, 1): image not found
