International ClassG10H 001/02Foreign Application Priority Data1986-05-26 JPAbstractA striker designed to strike or be swung for playing music is provided with a musical sound-initiating command signal-generating device including switching members. When the striker strikes or swings, the switching members perform a switching action which triggers the transmitting of a musical sound-initiating command signal from the musical sound-initiating command signal-generating device. A desired musical sound is produced by a musical sound producing unit in response to the musical sound-initiating command signal. A number of different timbres can be selectively used for a musical tone, by operating a timbre-selecting switch provided on the striker.Other References
