ABSTRACT:
A keyboard apparatus with at least one key having a rotation fulcrum and an exterior front end face on the opposite side of the rotation fulcrum in a performer side. The exterior front end face of the at least one key defines a front lower section. An extended section is provided at the front lower section of the at least one key that extends from the exterior front end face of the at least one key toward the performer side, and a mass member is attached to the extended section. The mass member therefore extends forwardly from the external front end face of the at least one key toward the performer side.
