### Dataset Summary
Mutopia guitar dataset consists of the soloist guitar pieces of the [Mutopia Project](https://www.mutopiaproject.org/). I encoded the MIDI files into text tokens using the excellent [implementation](https://github.com/AI-Guru/MMM-JSB) of Dr. Tristan Beheren of the paper: [MMM: Exploring Conditional Multi-Track Music Generation with the Transformer](https://arxiv.org/abs/2008.06048).
The dataset mainly contains guitar music from western classical composers, such as Sor, Aguado, Carcassi, and Giuliani.
### Supported Tasks and Leaderboards
Anyone interested can use the dataset to train a model for symbolic music generation, which consists in treating symbols for music sounds (notes) as text tokens. Then, one can implement a generative model using NLP techniques, such as Transformers.
## Dataset Structure
### Data Instances
Each guitar piece is represented as a line of text that contains a series of tokens, for instance:
PIECE_START: Where the piece begins
PIECE_ENDS: Where the piece ends
TIME_SIGNATURE: Time signature for the piece
BPM: Tempo of the piece
BAR_START: Begining of a new bar
NOTE_ON: Start of a new musical note specifying its MIDI note number
TIME_DELTA: Duration until the next event
NOTE_OFF: End of musical note specifying its MIDI note number
```
{
'text': PIECE_START TIME_SIGNATURE=2_4 BPM=74 TRACK_START INST=0 DENSITY=4 BAR_START NOTE_ON=52 TIME_DELTA=2.0 NOTE_OFF=52 NOTE_ON=45 NOTE_ON=49 TIME_DELTA=2.0 NOTE_OFF=49 NOTE_ON=52 TIME_DELTA=2.0 NOTE_OFF=45 NOTE_ON=47 NOTE_OFF=52 NOTE_ON=44 TIME_DELTA=2.0,
...
}
```
### Data Fields
- `text`: Sequence of tokens that represent the guitar piece as explained in the paper [MMM: Exploring Conditional Multi-Track Music Generation with the Transformer](https://arxiv.org/abs/2008.06048).
### Data Splits
There are, at this moment, 395 MIDI guitar files in the Mutopia Project. I removed files of pieces that were not music for soloist guitar. After this removal, there were 372 MIDI files.
I used an 80/20 split and augmented the training dataset by transposing the piece 1 octave above and below (24 semitones). The final result is then:
**Train dataset:** 7325 pieces
**Test dataset:** 74 pieces |
