ABSTRACT:
An auto-play apparatus associated with a keyboard instrument is arranged for generating auto-accompaniment tones such as chord, bass drum lines to have a specific rhythm pattern. When a player determines tone-up of a music piece during a performance, he or she operates an intonation dial (22) arranged on an operation panel (2) or an expression pedal (23). Then, an intonation value representing a tone-up level of the music piece is generated as numerical value information. A corresponding play pattern is read out from an auto-accompaniment pattern ROM (6) according to the intonation value and a rhythm pattern selected in advance upon operation of an operation member of the operation panel (2), thus starting an auto-play operation. Auto-accompaniment pattern data corresponding to the intonation value is programmed to change the play pattern according to a tone-up state of a music piece during the performance of the music piece.
