The keyboard includes a plurality of keys aligned on a musical instrument body. The fallboard is pivotally supported by the musical instrument body and to be closed/opened so as to cover/uncover the keyboard. The musical tone generating unit electrically generates a musical tone signal in response to a key depression on the keyboard under the control of control information which is provided by switches on the operation panel. The operation panel is located at a position opposite to a performer in the inner surface of the fallboard when the fallboard is open so that the performer can operate the operation panel during his performance at the keyboard.
