An electronic percussion instrument is constituted by a hi-hat, a stand, and a foot pedal, wherein the hi-hat is interlocked with the foot pedal via a movable shaft. In the hi-hat, a core plate (and a core) is arranged in the upper portion, and membrane switches are arranged in the lower portion and are covered with a rubber block, which is gradually brought into contact with membrane switches when depressed by the core plate, which is moved downwards upon depression of the foot pedal. In response to a depressed position of the foot pedal, membrane switches are sequentially turned on or off, thus producing a control signal whose value is varied to control an electronic sound in tone color. Thus, it is possible to produce various hi-hat sounds such as an open hi-hat sound, a closed hi-hat sound, and a foot hi-hat sound as necessary.
