Abstract
The present invention provides a musical instrument manual having keys that may be made of a material subject to warping and twisting, such as wood. A distal flexible suspension allows angular shifting of the distal end of each key of the manual to accomodate key warping. The flexible suspension enables angular displacement of the key lever about its distal end perpendicular to the plane of the playing surface of the key to allow the key to be played. The flexible suspension elastically opposes twisting of the key lever relative to the key bed.
