ABSTRACT:
A hammer stopper is moved into and outof an orbit of an extension of a hammer shank depending upon an operation mode, and the extension rebounds on the hammer stopper in an electronic sound producing mode between an escape of a jack from a butt and a strike of a hammer head at a set of strings so that a player performs a music through synthesized sounds without sacrifice of the piano key-touch.
