ABSTRACT:
An electronic musical instrument comprises a keyboard, tone signal forming circuit to produce musical tone signals corresponding to keys being depressed on the keyboard, a memory to store musical performance data representing pitches and durations of notes and durations of rests according to the progression of a musical performance, a keyboard indicator to visually indicate which keys are to be depressed on the keyboard in accordance with the performance data read out of the memory so that the pupil or trainee may effect a musical performance on the keyboard by following the key indications, and an automatic musical performance device to effect an automatic musical performance in synchronism with the musical performance to be effected on the keyboard. A control circuit for the memory is arranged such that the key indication for each note in the progression of music is effected in the period of the duration of the immediately preceding note or rest. In other word, when the trainee depresses each melody note, the indicator points the key for the succeeding note.
