A performance apparatus 11 extends in its longitudinal direction to be held by a player with his or her hand. The performance apparatus 11 is provided with a geomagnetic sensor 22 and an acceleration sensor 23. At the time when the geomagnetic sensor and acceleration sensor determine that the performance apparatus 11 is kept within a sound generation space and has been moved by the player, CPU 21 gives an electronic musical instrument 19 an instruction to generate a musical tone of a tone color corresponding to the sound generation space. The sound generation spaces and corresponding tone colors are stored in a space/tone color table in RAM 26. Upon receipt of the instruction, the electronic musical instrument generates a musical tone of a tone color corresponding to the sound generation space.
