ABSTRACT:
An improved wippen heel arrangement for an upright piano includes: a pillar screwed into one end portion of a piano key so that the projecting length of the pillar which projects from the piano key is adjustable; a wippen heel attached to a wippen constituting one element of an action mechanism; and a wippen joint interposed between the pillar and the wippen heel for pivotal movement about a stationary shaft, in which the thrust applied to the pillar is transmitted through the wippen joint to the wippen. Accordingly, a key touch quality which may be experienced with a grand piano can be enjoyed using an upright piano.
