Abstract
In drum head tensioning mechanism of or for a musical drum, an intermediate hoop assembly or cage is secured about the drum shell by end abutment therewith and supports top and bottom drum heads. Top and bottom counterhoops are provided about the drum heads and respectively engage flesh hoops on the drum heads. Upper and lower tensioning bolt assemblies connect the counterhoops to the intermediate hoop assembly, the lower bolt assemblies extending upwardly towards and interspaced with the upper bolt assemblies whereby all the bolt assemblies are accessible for conveniently and independently adjusting both top and bottom drum head tension. The interior of the drum shell also remains "clean" for optimum sound quality.
