ABSTRACT:
A keyboard instrument selectively enters into an acoustic sound mode for performing a music with acoustic piano sounds and an electronic sound mode for performing a music with synthetic sounds, and a rotary stopper is provided between hammer shanks and strings for interrupting a rotation of the hammer toward the strings in the electronic sound mode; wherein a cushion is provided on the rotary stopper for damping an impact of a damper leaving from the strings in both acoustic and electronic sound modes so that a player can perform a music without a noise.
