Abstract: An electronic percussion instrument and sound production control method thereof are provided. In an electronic cymbal, the output of a musical sound is controlled in accordance with the results of detection from a strike sensor when the strike sensor detects a strike on a striking surface. While the musical sound is output, if a user touches the striking surface, an electrostatic capacitance sensor outputs an output value in accordance with the contact condition so that the musical sound is attenuated in accordance with the output value while being output. Therefore, the user can attenuate the musical sound being output in accordance with the contact conditions on the striking surface, thereby silencing the musical sound by way of the action similar to that of the acoustic cymbal choke that is the action of touching the striking surface.
