PURPOSE:To facilitate the control of an arbitrary musical tone element variation by detecting an action of a wrist of a hand executing a sound pitch instruction operation in a guitar performing action, and controlling a musical tone element in accordance with an action signal corresponding to this action. CONSTITUTION:The subject controller is provided with an angle sensor 1 and an angle detecting circuit 15 being operation detecting means for detecting an action of a wrist of a hand executing a sound pitch instruction operation in a guitar performing action, and also, generating an action signal corresponding to this action, and a CPU 10 being a musical tone control means for controlling a prescribed musical tone element in accordance with its action signal. In such a state, the angle sensor 1 and the angle detecting circuit 15 being the operation detecting means detect an action of a wrist of a hand executing the sound pitch instruction operation in the guitar performing action and generate an action signal corresponding to this operation, and the CPU 10 being the musical tone control means controls a prescribed musical tone element in accordance with its action signal. In such a way, in the musical tone elements, for instance, an arbitrary pitch variation can be controlled easily. |
