ABSTRACT:
A keyboard assembly includes a plurality of white keys and black keys juxtaposed to each other and each having a body disposed to be depressed, and a connecting portion, and a key support that supports the body. The connecting portion connects the body to the key support in a fashion permitting the body to swing in directions of key depression and release while limiting lateral motions of the body. The body of each of the white keys has an extension formed integrally therewith and laterally extending therefrom at a location under the body of a corresponding one of the black keys in such a manner that the extension overlaps with the bottom surface of the body of the corresponding one of the black keys.
