# Optical Music Recognition of Jazz Lead Sheets - Staff Level Dataset
We provide musical scores for 163 unique jazz standards in MusicXML and Humdrum **kern format. The latter is widely used in systems that output musical scores, because it is a compact and easy-to-handle format.
The MusicXML scores are sourced from the Wikifonia database (discontinued in 2013) and have been partially corrected. We also leave the lyrics, if present in the original files, as they could be helpful for future extensions, but we don't consider them in this work.

## How to use it
Check the following example.

```python
from datasets import load_dataset


DATASET_NAME = "PRAIG/JAZZMUS_staffLevel"

ds = load_dataset(DATASET_NAME)

image = ds["train"][0]["image"]
transcription = ds["train"][0]["transcription"]
print(f"Image: {type(image)}")
print(f"Transcription: {repr(transcription)}")
```
