ABSTRACT:
A convertible drumhead easily mounted and tensioned on a conga shell, adaptable for use with any conventional drum shell and usable independently as a single headed hand held drum that is uniform in construction and comprises a drumming surface, a circumferential side wall integrally formed with and disposed around the periphery of the drumming surface and an annular shoulder, which includes a seat portion along its top surface. The sidewall and the annular shoulder can be fashioned as a one-piece unit or as separate pieces where the shoulder is fixed in abutting relationship against the side wall. The invention is used in combination with a ring or a modified version of a standard rim mounted counter-hoop, which abuts against the side wall and is supported tightly upon the seat of the annular shoulder. The shoulder, when employed as a separate component, securely anchors itself to the side wall and, thus, will integrate with it to ensure the integrity of the drumhead. In doing so, the shoulder will withstand the stress forces that it normally experiences during the tensioning process to prevent its separation from the side wall.
