An input device includes a movement and orientation sensor for detecting one of a movement or an orientation of the input device itself. Firstly, information about one of the movement or the orientation of the input device having been detected by this movement and orientation sensor is obtained. Next, a difference between the orientation of the input device having been obtained, and a predetermined reference orientation is calculated. A predetermined sound is produced based on the difference in orientation, thereby executing music performance. |
