1. An electronic hi-hat comprising:
a rod movable up and down in accordance with an operation of a player;
a top cymbal, including a striking surface, that can be struck by the player and movable up and down in accordance with a movement of the rod;
a bottom cymbal attached to face the top cymbal, the bottom cymbal capable of coming into contact with or separating from the top cymbal that moves up and down in accordance with the movement of the rod; and
a detector capable of detecting a separation dimension between the top cymbal and the bottom cymbal,
the detector detects separation dimensions of a plurality of areas that are displaced with angular inclinations of the top cymbal and the bottom cymbal with respect to the rod, and the plurality of areas where the separation dimensions are detected are located on a common circumference of the top cymbal and the bottom cymbal around the rod as a center;
the detector includes a distance sensor, including a sensor and a reflection surface, one disposed in the top cymbal and the other disposed in the bottom cymbal, the distance sensor is capable of detecting, in a non-contact manner, the separation dimensions of the plurality of areas that are displaced with the angular inclinations of the top cymbal and the bottom cymbal with respect to the rod.
