PROBLEM TO BE SOLVED: To provide a performance practicing apparatus that makes clearly recognizable on a music sheet the correctness or incorrectness of each tone played and the relationship of correspondence between each played tone and the matching note on the music sheet.SOLUTION: A CPU sets a part boundary note within a graphic drawing range containing the current bar in which the cursor is positioned in a displayed music sheet. It distinguishes and displays as a pertinent tone a note within the graphic drawing range matching performance data Note at the same tone pitch as the pressed key tone and, if the pertinent tone is included in the right hand part (or the left hand part), draws a tone pitch line representing the same tone pitch as the pressed key tone within the graphic drawing range, and draws a mark a half tone below, or a half tone above, on a note positioned on the same one of the five lines as the tone pitch line but a half tone lower or a half tone higher than the pressed key tone.
