Radif Corpus; Symbolic Dataset for Non-Metric Iranian Classical Music

We introduce the first digital corpus representing the complete non-metrical Radif repertoire, the foundational repertoire of Iranian Dastgah music. We provide MIDI files (around 16825 seconds in total) and data spreadsheets describing notes, note durations, intervals, and hierarchical structures for 228 pieces of music. Quarter-tones are represented using symbolic extensions (e.g., Ak) in the notation, where k denotes a quarter-tone modification. In MIDI, quarter-tones are represented using pitch bend. Furthermore, we provide supporting basic statistics, measures of complexity and similarity over the corpus.
