ABSTRACT:
A musical tone control apparatus includes at least one grip device having the shape which can be held by player's hand. This grip device further includes plural push switches each having a piezoelectric element whose resistance is varied in response to depressing pressure applied thereto. Based on a combination of depressed push switches and its depressing pressures, an externally provided musical tone generating apparatus is controlled such that tone pitch, tone color, tone volume, touch response or the like of musical tone will be controlled. In addition, an angle detector for detecting a swing movement of a player's arm can be further provided. Thus, the detected swing movement of the player's arm can be additionally used for controlling the musical tone.
