Abstract: An electronic instrument 4 includes a first cymbal 11comprising metal. The first cymbal 11 is electrically conductive. Furthermore, the electronic instrument 4 includes a capacitance-type touch sensor 43, and the first cymbal 11 is used as a touch electrode of the touch sensor 43. Thus, when a performer with capacitance touches the first cymbal 11, the line-to-ground capacitance of the first cymbal 11 changes, and a signal corresponding to the change in line-to-ground capacitance is output from the touch sensor 43. Therefore, when the performer touches the first cymbal 11 in the same manner as when muting a conventional cymbal, a signal indicating mute can be output from the touch sensor 43.
