PURPOSE:To properly practice a musical performance while grasping the whole flow of music regardless of how much the musical performance is mastered by carrying out repetitive practices at intervals of specific sections of music and a performance practice of the whole music. CONSTITUTION:When a lesson mode is started initialization is performed first (steps S1-S4) and performance data in an address ADR are read out of a ROM (step S5). When a melody flag LF indicates '0', a 1st repetitive performance is judged and sound generation or elimination based upon the performance data is performed (steps S6-S11). When the 1st performance is performed up to the end of a phrase (steps S12), the melody flag LF and an alarm flag PF are set to '1', the address ADR is set to a phrase head address FSD (steps S15-S17), and an alarm is sounded (steps S21-S24). In a 2nd repetitive performance, the melody part is not played and only the base part is played (steps S8-S11). |
