Abstract
When a tap switch is operated at desired beats during automatic music play, the tempo of the automatic play is variably controlled in correspondence with the interval between the tap operations. On the other hand, detection is made of a difference between the current score time at a tap switch operation time and the score time of a beat point corresponding to the tap switch operation time. Then, control is made for progressively changing the current score time in order to eliminate the detected score time difference. Thus, the score time difference is progressively eliminated in smooth manner, so that necessary notes can be sequentially sounded without being left out. The control for progressively changing the current score time may be performed in accordance with a predetermined function. Further, the control for progressively changing the current score time may be performed with a characteristic such that it is automatically changed in view of the number of notes in the automatic play.
