Abstract: An acoustic-drum tuning assembly includes a single adjustment feature to vary the drumhead tension uniformly around the drumhead's periphery. The tuning mechanism includes multiple rings located between the end of the drum shell (or support ring) and the “underside” of the drumhead, which is otherwise restrained with respect to the drum shell by a hoop or rim fixed in place by threaded tension rods and lugs or other hoop-fixing mechanism.
