An apparatus is to analyze music data of a musical performance including note events of triplets as well as note events like triplets, and to display the note events in triplet notation properly in view of the general rhythmic tendency of the musical performance. Music data representing a musical performance is analyzed by counting the number of note events which occur as a regular rhythm pattern and the number of note events which occur as a triplet, so that the performed music as a whole is judged to be either in a triplet-shy rhythm or in a triplet-rich rhythm. Then fuzzy triplet detecting time windows detect triplet candidate notes. Thus detected fuzzy triplet note events are flexibly decided to be notated in a regular rhythm pattern form or in a triplet form depending on whether the performed music as a whole is in a triplet-shy rhythm or in a triplet-rich rhythm. The notes are displayed in the decided form of notation to provide a good-looking and easily understandable music score.
