SOLUTION: When a performance is started, at designated time intervals, an accompaniment part of the music piece data is transferred to a performance part and reproduced. In the case where a vocal part is existent in the musical piece data in the process of performance, the frequency of voice input from a microphone is detected and converted to a musical interval. The interval input from the microphone is compared with the interval of the vocal part corresponding to the musical piece data in the process of reproduction to calculate a difference in interval. In the case where the difference in interval is shifted from an allowable range, the interval input from the microphone is displayed in a color different from the color of the notation on a notation display part 203, and a demerit mark is given. Thus, the calculated marks are displayed on a mark display part 240. |
