    Abstract: A keyboard instrument, in particular a piano, has a keyboard (11) with a multiplicity of keys (12) and also at least two supporting elements (21, 22) for supporting the keyboard (11). A panel-form keybed (10) made of a wood material forms a console, and therefore a rest for the keyboard (11). It is Borne by the at least two supporting elements (21, 22). A groove (33) is provided in the keybed (10). The groove (33) in the keybed (10) is provided parallel to an imaginary connecting line (23) between the two supporting elements (21, 22) and perpendicularly to the keys (12). The groove (33) is arranged on the underside (31) of the keybed (10). A threaded rod (41) is positioned in the groove (33). The keybed (10) can be prestressed by means of the nuts (37, 38) which are arranged in the keybed (10) and surround the threaded rod (41).

    Abstract: A long part-mounting structure of a piano, which makes it possible to mount a long part as a component part of a piano to a mounted member without causing warpage of the long part and maintain excellent appearance of the piano even when applied to a transparent piano. This long part-mounting structure is for mounting a keyslip as a component part of the piano to a keybed over the entire longitudinal length of the keyslip. The keyslip has a contact surface in contact with the keybed over the entire longitudinal length of keyslip and a mounting protrusion extending the entire longitudinal length of the keyslip and protruding a predetermined length toward the keybed from the contact surface. The keybed has a contacted surface with which the contact surface of the keyslip is brought into contact and a long groove into which the mounting protrusion is fitted.
