ABSTRACT:
An electronic musical instrument comprises a keyboard arranged to produce key code signals in response to key operations thereof and a memory storing performance data constituting progression of a music and corresponding to key operations to be effected on the keyboard to play the music. A key operation judging circuit is provided which compares the key code signals produced by the keyboard with the performance data read out of the memory to detect whether or not a pupil or trainee correctly operates keys in a corresponding relation to the performance data read out of the memory. The percentages of correct key operations are calculated and displayed with respect to the key-on timing and the pitch and duration of notes.
