ABSTRACT OF THE DISCLOSURE The flexible diaphragm sheet of a drumhead of a drum as a musical instrument is apertured in a manner often done by drummers to enhance the sound emitted by the drum, but, in accordance with the invention, the aperture is rigidly framed about its defining margin to substantially reestablish the vibrational integrity of the diaphragm and to protect it against splitting and cracking. Framing may be accomplished integrally with the diaphragm sheet in drum fabrication originally, or may be accomplished by securely clamping a frame in place about the defining margin of the aperture in existing drumheads or during original fabrication of drumheads.
