Abstract: A drum has an attachment assembly for tensioning one or more drum heads, and for mounting drum peripherals without piercing the drum shell. The attachment assembly tensions the drum heads to the shell by use of a separate, circumferential tension hoop and gasket-like “isolators” that isolate the tension hoop from drum-shell vibrations. This assembly reduces tonal alterations inherent in drum designs of the art, in which components are rigidly fastened to the drum shell. Rather than using common tension rods and lugs, this attachment assembly enables tuning/tensioning via the tension hoop. The tension hoop obviates the use of multiple lugs and hardware that commonly pierce a drum shell and preserves a continuous and homogeneous resonant drum shell. The tension hoop also enables differing top- and bottom-head tensions.
