Abstract: A tuning assembly and tunable drug system are described. The tuning assembly including a pressure ring, a rope ring with a first plurality of holes and a second plurality of holes, a rope system coupled to the first plurality of holes and a membrane of a drum head, and a plurality of fasteners engaging the second plurality of holes in the rope ring and a surface of the pressure ring. Tightening the plurality of fasteners increases the distance between the rope ring and the pressure ring causing the rope ring to pull the rope system and apply pressure to the membrane of the drum head.

Abstract: A drum that is configured as various alternate styles of drums wherein the present invention is operable to provide an improved sound resonance during play thereof. The drum of the present invention includes a shell that has an upper end and a lower end. The shell includes an opening located and the upper end and lower end and the shell is hollow therebetween. The opening at the upper end of the shell includes a membrane stretched thereover. The shell includes at least one aperture formed in the outer wall thereof. The aperture formed in the outer wall is oval in shape in a preferred embodiment and is configured to provide improved airflow and sound resonance during the playing of the drum of the present invention. Alternate embodiments of the present invention include a shell having different quantities of apertures based on the size of the shell.

Abstract: A drum having modified tone qualities is provided. The drum has a generally cylindrical inner shell positioned within a generally cylindrical outer shell. The inner shell has at least one sound-transmitting aperture defined therethrough so that the sound-transmitting aperture provides an unobstructed passageway for sound waves to pass through to reach the outer shell. In some aspects, an insert for modifying the tone qualities of a drum is provided. In some aspects, the outer shell has one or more inwardly extending protrusions co-located with and extending through the at least one sound transmitting aperture.

Abstract: An enhanced collapsible drum provides for a collapsible and expandable drum that in its collapsed state provides for improved portability and storage, while in its expanded state maintains the look, feel and playing quality of a drum having a traditional unibody shell or base design. The collapsible drum may be comprised of an elongated base or shell portion divided into two or more sections which may be nested in the collapsed position and can be extended and locked together by mating interlocking components to form an elongated drum base or shell in the expanded position. The collapsible drum may additionally include an internal lighting device and control responsive to sound. The collapsible drum may also include a case, handles and a strap for carrying or supporting the drum while playing or for securing the drum sections in the closed position.
