PURPOSE:To form a practice form being suitable for mastering completely the whole melody without leaving the part which cannot be performed. CONSTITUTION:In a monitor musical performance processing (SA2), the part in which there is a musical performance miss in music data of a one-music portion is extracted in a register MAn, for instance, such as MA0=2, MA2=8.... Subsequently, in the next SA3, in the case of being not (n)=0, it is the case when there is a musical performance miss in the monitor musical performance, and in this case, after a counter (m) executes '0' reset (SA6), data of a register MAm is read out by setting (m) as a pointer (SA7). Moreover, melody data between measures of MAm-th to (MAm+1)-th parts is read out, and musical performance practice corresponding to this part is executed. In such a state, in the case this part can be performed without a miss, and also, the whole one melody can be performed completely by a second monitor musical performance processing (SA2), the selected melody is stepped up in SA5. |
