Abstract
A drum tensioning system adapted to place a minimum of stress on the drum shell has a plurality of C-shaped clips acting on the counterhoop to apply tension to the drum head. The head passes over a cylindrical side wall which has flanges extending radially outwardly. The tensioning bolts pass through apertures in the flanges directly beneath the C-clips and are threaded into the base of the C-clips. The C-clips and counterhoop have mating surfaces which provide stability to the system. The side wall is attached to the drum shell.
