PROBLEM TO BE SOLVED: To provide a unit and method for guiding a performance at a low cost although the performance guide of right-hand and left-hand parts is given to a player who plays music having a plurality of parts. SOLUTION: A CPU 3 of a keyboard musical instrument 100 outputs musical sound data corresponding to tracks of right-hand part data 51a and left-hand part data 51b to a sound source 7 to reproduce the music. At this time, the CPU 3 generates an illumination signal according to operation guide data corresponding to the tracks of the right-hand part data 51a and left-hand part data 51b and outputs the signal to a guide part 4, which makes LEDs corresponding to the right-hand part blink in normal blinking pattern and LEDs corresponding to the left-hand part blink in reverse blinking pattern. Further, the CPU 3 judges whether correct playing operation is done at a playing operation part 1 and advances to a next track when the correct playing operation is done. |
