Jazzmus: Jazz Lead Sheets with Expert OMR Annotations

Jazzmus provides approximately 1,000 expert-annotated jazz lead sheets for Optical Music Recognition (OMR), developed by the PRAIG research group in 2025. The dataset includes high-resolution images paired with system-level bounding boxes and musical encodings for end-to-end transcription tasks.

Use Cases

• System-level segmentation using the 'bounding boxes' found within the 'annotation' column
• End-to-end music transcription from the 'image' source to the 'encoding' text format
• Text retrieval for specific musical patterns within jazz-specific notation

Strengths

• Expert-generated manual annotations for high label reliability
• Includes system-level bounding boxes for precise layout analysis
• Paired image and text encoding supports end-to-end OMR model training

Limitations

• Small sample size of fewer than 1,000 records
• Niche focus on jazz lead sheets may not generalize to complex orchestral or classical scores
• Restricted to non-commercial use under CC BY-NC 4.0 license
