Abstract
A musical drum is reinforced by a stiffening ring which is placed inside the shell of the drum at the edge adjacent to the drum head, and is adjusted by a screw to provide internal tension in the drum shell to prevent its being squeezed when the drum head is tightened. The stiffening ring additionally forms the open head, the bearing edge, of a wooden drum into a truer round, i.e. cylindrical, shape. This provides more accurate and precise tuning.
