A table-type electronic percussion instrument is constructed of a table top, legs, pads as well as a musical-tone-generation circuit and a speaker system. Herein, the table board has a specific shape such as a pentagon-like shape which enables a number of persons to sit at it. The table top is supported by the legs and is constructed of a base material having a high rigidity and a finishing board like plywood. The finishing board covers a surface of the base material through which holes are formed. The pads are arranged on a surface of the dressing board to coincide with the locations of the holes. Sensors are provided inside of the holes and are attached to the backside of the finishing board. Thus, the sensors are arranged to detect a striking force imparted to any of the pads by a person. The musical tone generation circuit is provided beneath the table board to convert electric signals from the sensors to musical-tone signals. The speaker system is located beneath the table board to generate musical tones (e.g., percussion sounds) based on the musical-tone signals. For example, if the pads are to be reproduce electronic drums and/or electronic cymbals, the speaker system generates drum sounds and/or cymbal sounds when the pads are struck. Thanks to the table-like construction, the electronic percussion instrument can be shared by a number of persons to play an ensemble. Incidentally, the musical-tone-generation circuit contains a mixing circuit which performs mixing operations on the musical-tone signals corresponding to the pads and other musical tone signals supplied thereto. Thus, the musical-tone- generation circuit outputs mixed musical-tone signals, based on which the speaker system generates mixed musical sounds.
