  • Compact device for adjusting piano key touch weight
    Publication number: 20100288103
    Abstract: A series of adjustable springs, rigidly suspended above the keys of a piano, provides a downward force which reduces the effort needed to depress the keys. Precise adjustment of the series, and its attachment to the piano are facilitated through the use of existing fastener hardware within the conventional piano architecture.
