The fallboard is pivotally supported by the musical instrument body and to be closed/opened so as to cover/uncover the keyboard.

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.
