  • Apparatus and methods for modifying piano keyboards
    Patent number: 6020549
    Abstract: Aspects of the present invention provide relatively inexpensive methods and apparatus for modifying existing pianos to provide interchangeable keyboards of different sizes without sacrificing or impairing the quality of the original piano. The keys of a standard piano are removed and the pins in the front rail of the key frame are replaced with pins which are more closely positioned. The original keys are then replaced with new keys of narrower dimensions which are more closely positioned in the area of the front rail.
