PROBLEM TO BE SOLVED: To realize a device and method for guiding on how to play capable of guiding a player in not only respective key positions to be operated by both left and right hands, but also the playing sequence of the positions. SOLUTION: This device compares an event elapsed time TR of the right hand part with an event elapsed time TL of the left hand part, and judges which part is to go ahead; when the right hand proceeds, an emitting means 2a of the keys designated by the playing data PD of the right hand part is made to flicker in red; and when the key-on timing is getting close and enters a double frequency flickering period t, the flickering means 2a is made to flicker at a double frequency and is turned on in red at the key-on timing. On the other hand, when the left hand proceeds, the emitting means 2a of the keys designated by the playing data PD of the left hand part is made to flicker in green; and when the key-on timing is getting close and enters a double frequency flickering period t, the flickering means 2a is made to flicker at a double frequency and is turned on in green at the key-on timing. |
