Abstract
A musical performance processing apparatus that provides better assistance for student's practice. The apparatus includes a main unit in which music data including performance information of right- and left hand parts is stored, and a performance terminal having a keyboard divided into two key ranges by a split point. Each key range is set as a tapping or normal performance key range. The main unit generates a musical tone when input with performance information generated by depression of a key in the normal performance key range, and automatically reproduces performance information of designated part of music data for the number of beats corresponding to key depression, when input with performance information generated by depression of a key in the tapping performance key range. Sounding is stopped, if there is a deviation between a tempo of teacher's tapping performance and timing of student's performance.
