Abstract (en)
[origin: WO0159752A1] The invention relates to a grand piano action comprising a hammer jack (4), a repetition lever (5) that is independent therefrom, and a hammer roller (8a), which is arranged on a hammer shank (6). Said hammer roller is located at a customary distance from the hammer jack (4) and is in contact with the repetition lever (5). The grand piano action is characterized in that the hammer roller (8a) is mounted such that it can rotate around the axis thereof. As a result, the exertion of force required for pressing down the key is reduced and playing is made easier.
