There is provided a performance apparatus which is capable of performing fine variable control of musical tone parameters so as to obtain a variety of sounding characteristics. A plurality of reeds are fixedly mounted on a center block and each excited to vibrate by a corresponding actuator. A plurality of, e.g. three, resonant plates of different sounding volume are arranged in layers and each provided with a short yoke. A plurality of, e.g. three, vibration transmission mechanisms are fixed on a lower surface of the center block in association the respective resonant plates, and each comprised of a clutch coil wound around a clutch yoke. A CPU controls the supply of driving current to a selected one of the vibration transmission mechanisms according to performance data so that the selected vibration transmission mechanism operates, and when the clutch yoke of the operating vibration transmission mechanism adsorbs the short yoke, the center block and the corresponding resonant plate are brought into a coupled state through the vibration transmission mechanism, whereby vibration of any of the reeds is transmitted from the center block to the resonant plate through the vibration transmission mechanism, to cause the resonant plate to vibrate.
