CASD

The Chordify Annotator Subjectivity Dataset (CASD) provides a reference dataset for harmony annotations in popular music, specifically focusing on annotator subjectivity. It includes multiple expert annotations for fifty songs, each evaluated by four annotators, and is encoded in JAMS format, along with metrics for reported difficulty and annotation time. This dataset aims to enhance research in Music Information Retrieval by addressing the variability in chord labeling among experts.
