Chord-Llama/chord_llama_dataset

The dataset used to train Chord Llama, A model for generating sheet music. This dataset contains entries of an altered version of the MusicXML format, and cannot be used to generate MusicXML directly. A fine-tuned model and interface will be released in the future.

The data is sourced from Wikifonia and Part 1 of MScoreLib. Both of these databases are originally in MusicXML format.

• Wikifonia: http://www.synthzone.com/forum/ubbthreads.php/topics/384909/Download_for_Wikifonia_all_6,6

• MScoreLib: http://mscorelib.com/

Please see music_xml_converter.ipynb for the notebook used to generate the dataset.

The data was then cleaned to maximize tokenization in a few ways:

• Everything that added readability to the file without changing the meaning of the music was removed
• All parts were separated into individual documents
• All parts containing more than one <attributes> element were discarded
• The MusicXML was converted into YAML format to lower token count using the Python library xmltodict
• If the necessary data of the YAML version of the document was over Llama 2's context length, the document was split
• The <attributes> element saved to instruction
• The first half of the measures was set to the input
• The second half of the measures was set to the output
