Composition of music with reinforcement learning.
As of now, this is a proof-of-concept for music composition by reinforcement learning agents. Here, an agent interacts with piano roll environment, episode end is submission of current piano roll, and reward is determined by applying evaluation rules to the roll.
Comparing to music composition tools such as MuseNet, reinforcement learning approach (at least in theory) has two advantages:
- Actual creativity lies not in imitation of famous pieces, but in finding new ways to create something to be called art. Reinforcement learning meets this criterion, but supervised learning don't.
- There are tuning systems other than equal temperament (say, in microtonal music) and there can be not enough pieces for some of them. A model can not be trained in a supervised manner without a dataset, but, given evaluation rules, an agent can be trained even for an absolutely new tuning system.
Currently, the implementation of environment supports only equal temperament, but this limitation may be eliminated in the future.
To find more details, look at a draft of a paper.
To install a stable version, run:
pip install rl-musician
To train an agent from scratch and to get results produced by it, run:
python -m rlmusician \ -c [path/to/your/config] \ -p [how_long_to_train] \ -e [how_many_pieces_to_produce]
All three arguments are optional. Default config is used if
-c argument is not passed;
-e options have reasonable defaults too.
Created pieces are stored in a directory specified in the config. For each piece, there is a nested directory that contains:
- Piano roll in TSV format;
- MIDI file;
- Events file in sinethesizer TSV format;
- WAV file.
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
