Which comprises a keyboard for a musical instrument, organ, piano or any other system with a keyboard for producing musical or other sounds, which consists of a plastic, wooden, etc., base, on which one flexible plate is fitted for each key, although at the end at which they are attached to the base they can be all joined. The keys, base or frame and other components of the keyboard may be made of plastic, wood or any other material. The keys must all be of the same height and rectangular in shape Fig. 1, although they may adopt another different shape, like the keys producing flats and sharps in the musical scale being shorter and narrower Fig. 3, or they may be identical in shape and size, but to differentiate between them they may have a different colour or shade Fig. 2. <IMAGE>
