PROBLEM TO BE SOLVED: To provide a musical performance learning device which allows a fine lesson with small scaled device. SOLUTION: When a lesson mode is set, a keyboard 2 is split into a student area 2A and a tutor key area 2B. When keys are operated in the tutor key area 2B, a sound is generated at the pitch corresponding to the keys in the student area 2A which are 2 octaves lower than the operated keys. At the same time, the LEDs provided to a navigator 3 corresponding to the keys are turned on and off to indicate the keys which should be operated in the student area 2A. |
