ABSTRACT:
A jack on a whippen incorporated in an upright piano drives a hammer assembly to rotate toward musical strings for producing sound, and a soft pedal causes the hammer assembly to become closer to the musical strings, wherein the upright piano comprises an adjusting mechanism operative to move the whippen upon manipulation of the soft pedal for eliminating gap between the jack and the butt as well as modifying rotating distance of the whippen, and a driving link assembly coupled between an associated key and a damper mechanism so that the whippen moved by the adjusting mechanism has no influence of action of the damper mechanism, thereby keeping key-touch ordinary under the manipulation of the soft pedal.
