ABSTRACT:
A keyboard apparatus for musical instruments such as pianos, organs, clavichords, and harpsichords, and methods for making and using the apparatus. The apparatus includes a frame assembly, a plurality of keys, a plurality of lever assemblies each operably connected with its corresponding key, and a main fulcrum that together replicate the touch of an acoustic piano keyboard. It can be used in electronic and acoustic instruments, can be adjusted to simulate the feel of a selected type of keyboard instrument, and is simple and cost-effective to manufacture.
