The mung
(Music Notation Graph) package implements a graph representation
of music notation that is especially amenable to Optical Music Recognition (OMR).
It was used for instance in the MUSCIMA++ dataset of music notation.
Requires Python >= 3.6 and was tested with Python 3.11.
pip install mung
Fundamentally, the Music Notatation Graph is a very simple construct:
It stores the primitives that can be detected by a Music Object Detector as nodes and then store the relations between those nodes. But the devil is in the details. To better understand what kind of relations are useful and which kind of relations are stored for common western music notation, check out the annotator instruction from MUSCIMarker.
The dataset itself is available for download here and due to its derived nature, licensed differently:
