Abstract

A tuning mechanism for tuning a drum having a head and a shell. The tuning mechanism includes a tuning bracket or receptacle mounted to the shell with a stabilizing portion formed thereon. A tuning rod has a first end attached to the head of the drum for varying the tension on the head and a second end passing through the tuning bracket and fitted with a nut for varying the applied tension to the head of the drum. Further a stabilizing washer positioned between the nut and the tuning bracket to improve a tuning procedure for said drum, whereby the stabilizer washer has a stabilizing tang that engages the stabilizing portion on the tuning bracket to prevent unwanted contact between the threads of the tuning rod and other structure of the percussion instrument.
