Abstract
A system for stretching and tuning a drumhead includes a plurality of bolts each provided with a threaded shank and at least one associated nut threaded thereon. Each bolt is secured circumferentially and substantially equi-angularly about the periphery of the drum shell. The system includes a flexible, elongate member that is woven alternatively between the drumhead and each of the bolts until the elongate member is taut. Thereafter, the bolt shanks may be rotated relative to the bolt nuts so as to pull the elongate member into a more taut tension, whereby the condition of the drumhead increases. A drum including the system, a kit for implementing the system, and a method of implementing the system are also disclosed.
