This paper presents an automatic system for the detection of single- and multi-note ornaments in Irish traditional flute playing. This is a challenging problem because ornaments are notes of a very short duration. The presented ornament detection system is based on first detecting onsets and then exploiting the knowledge of musical ornamentation. We employed onset detection methods based on signal envelope and fundamental frequency and customised their parameters to the detection of soft onsets of possibly short duration. Single-note ornaments are detected based on the duration and pitch of segments, determined by adjacent onsets. Multi-note ornaments are detected based on analysing the sequence of segments. Experimental evaluations are performed on monophonic flute recordings from Grey Larsen’s CD, which was manually annotated by an experienced flute player. The onset and single- and multinote ornament detection performance is presented in terms of the precision, recall andF -measure.
