Abstract
An electronic musical instrument can be provided with a control unit capable of arbitrarily shifting a tone pitch of a key within a keyboard from its reference tone pitch. This control unit includes a plurality of pitch-bend switches to which predetermined pitch values are respectively assigned. Each of these pitch-bend switches has a shape which can be easily operated by a player with high speed. The tone pitch of each key can be incremented or decremented by the predetermined pitch value from its reference tone pitch when the switches are operated by the player.
