Electronic musical instrument

Abstract

Abstract PURPOSE:To realize the effective self-learning of play practice by storing play information for specifying play operated keys and displaying a correct play rate based upon the result of comparison between the read play information and play information generated as keys are operated. CONSTITUTION:For example, the play information specifying play operated keys is read out of, for example, a score 12 and written and set in a storage device 11. The stored play information is read out by a read circuit 14 in play order and latched and stored in a data latch circuit 16 in order. The play information generated as keys on a keyboard 17 are operated is sounded by a speaker 20 through a musical sound generating circuit 18 and also supplied to a correct keying judging circuit 21. The correct keying judging circuit 21 sends out a correct keying signal to a marking circuit 22 when judging that a key corresponding to the play information latched in the latch circuit 16 is operated. The marking circuit 22 is supplied with the number of events from a modulus counter 23 and the calculated correct operation rate is displayed on a display circuit 24 at any time. Thus, the self-learning of play practice is carried out effectively.
