<p>PURPOSE:To enable a non-hit-string musical performance wherein no hit string sound is generated and a normal musical performance without obstructing a touch on a key by varying the period of the leaving of a hammer assembly from a jack. CONSTITUTION:This keyboard musical instrument is equipped with tensed strings 1, the hammer head 13 of the hammer assembly which rotates to hit the strings 11, the jack 33 which pushes up the butt 15 of the hammer assembly to move the butt 15 away, the key which transmits a force to this jack 33, a hammer stopper 120 which impedes the string hitting of the hammer head 13, and a regulating bracket 101 which makes the period wherein the butt 15 leaves the jack 33 earlier when the string hitting is impeded by the hammer stopper 120 than when the strings are hit.</p> |
