PDMX: A Large-Scale Public Domain MusicXML Dataset for Symbolic Music Processing

We introduce PDMX: a Public Domain MusicXML dataset for symbolic music processing. Refer to our paper for more information, and our GitHub repository for any code-related details. Please cite both our paper and our collaborators' paper if you use this dataset (see our GitHub for more information).

Upon further use of the PDMX dataset, we discovered a discrepancy between the public-facing copyright metadata on the MuseScore website and the internal copyright data of the MuseScore files themselves, which affected 31,221 (12.29% of) songs. We have decided to proceed with the former given its public visibility on Musescore (i.e. this is what the MuseScore website presents its users with). We have noted files with conflicting internal licenses in the license_conflict column of PDMX. We recommend using the no_license_conflict subset of PDMX (which still includes 222,856 songs) moving forward.

Additionally, for each song in PDMX, we not only provide the MusicRender and metadata JSON files, but we also try to include the associated compressed MusicXML (MXL), sheet music (PDF), and MIDI (MID) files when available. Due to the corruption of 42 of the original MuseScore files, these songs lack those associated files (since they could not be converted to those formats) and only include the MusicRender and metadata JSON files. The all_valid subset of PDMX describes the songs where all associated files are valid.
