PROBLEM TO BE SOLVED: To provide a technology for displaying movements of hands and fingers during playing in such a style that a user can easily understand them. SOLUTION: The tip part from the wrist is divided into a hand part and five finger parts. The finger parts are each further divided into three parts. Keying operations of the finger parts start before corresponding musical sounds begin to be generated and key releasing operations start when the musical sound are muted. Keying operations by finger underpassing or overpassing are done when predetermined conditions are all met. A finger part after key releasing is placed in a slack state when not used for next keying. The hand part is moved on an xy plane according to the position of a key to be pressed, the kind of a finger part used for the keying, etc. Operations for pressing a plurality of keys to sound the constituent sounds of a chord are represented by moving the position of the hand part on a z axis. Thus, a series of successive playing operations is displayed as a moving picture. |
