GPT-2 for Music

Language Models such as GPT-2 can be used for Music Generation. The idea is to represent pieces of music as texts, effectively reducing the task to Language Generation.

This model is a rather small instance of GPT-2 trained the Lakhclean dataset. The model generates 4 bars at a time at a 16th note resolution with 4/4 meter.

Model description

The model is GPT-2 with 6 decoders and 8 attention heads each. The context length is 2048. The embedding dimensions are 512.

Model family

This model is part of a huge group of Transformers I have trained. Most of them are not publicly available.

If you are interested in using andor licensing one of the models, please get in touch.

Lakhclean

These models were trained on roundabout 15K MIDI files (the same as the model you are viewing now) from the Lakhclean dataset.

lakhclean_mmmbar_4bars_d-2048: 4 bars resolution, bar inpainting, note density conditioning
lakhclean_mmmbar_8bars_d-2048: 8 bars resolution, bar inpainting, note density conditioning
lakhclean_mmmtrack_4bars_chords: 4 bars resolution, chord conditioning
lakhclean_mmmtrack_4bars_d-2048: 4 bars resolution, note density conditioning (this model)
lakhclean_mmmtrack_4bars_simple-2048: 4 bars resolution
lakhclean_mmmtrack_8bars_d-2048: 8 bars resolution, note density conditioning

Lakhfull

These models were trained on roundabout 175K MIDI files from the Lakh dataset.

lakhfull_mmmtrack_4bars_d-2048: 4 bars resolution, note density conditioning (the big brother of this model)
lakhfull_mmmtrack_4bars_simple-2048: 4 bars resolution

Metal

These models were trained on roundabout 7K MIDI files from my own collections. They contain genre conditioning.

metal_mmmbar_4bars_d-2048: 4 bars resolution, bar inpainting, note density conditioning
metal_mmmbar_8bars_d-2048: 8 bars resolution, bar inpainting, note density conditioning
metal_mmmtrack_4bars_d-2048: 4 bars resolution, note density conditioning
metal_mmmtrack_8bars_d-2048: 8 bars resolution, note density conditioning

MetaMIDI Dataset genres

These models were trained on genre-specific subsets of the MetaMIDI dataset.

mmd-baroque_mmmtrack_4bars_d-2048: 4 bars resolution, note density conditioning
mmd-baroque_mmmtrack_8bars_d-2048: 8 bars resolution, note density conditioning
mmd-classical_mmmtrack_8bars_d-2048: 8 bars resolution, note density conditioning
mmd-noncontemporary_mmmtrack_8bars_d-2048: 8 bars resolution, note density conditioning
mmd-pop_mmmtrack_8bars_d-2048: 8 bars resolution, note density conditioning
mmd-renaissance_mmmtrack_8bars_d-2048: 8 bars resolution, note density conditioning

MetaMIDI Dataset full

These models were trained on roundabout 400K MIDI files from the MetaMIDI dataset.

mmd-full_mmmtrack_4bars_d-2048: 4 bars resolution, note density conditioning
mmd-full_mmmtrack_8bars_d-2048: 8 bars resolution, note density conditioning
mmd-full_mmmtrack_4bars_chords-d-2048: 4 bars resolution, note density conditioning, chord conditioning (most powerful model in the entire group)

Intended uses & limitations

This model is just a proof of concept. It shows that HuggingFace can be used to compose music.

How to use

There is a notebook in the repo that you can use to generate symbolic music and then render it.

Limitations and bias

Since this model has been trained on a very small corpus of music, it is overfitting heavily.
