摘要

The blade (DO) has a thinned part located at a sound end of the blade, and a thick part located at a north end of the blade for allowing fixation of the blade on a percussion keyboard instrument such as piano, where the thinned part is struck. The blade is suspended by cords (1, 2) passing in the north and south ends of the blade of the percussion keyboard instrument. An independent claim is also included for a percussion keyboard instrument composed of multiple blades.
