The present disclosure relates generally to a drum apparatus with advanced acoustic response and methods of manufacturing the drum apparatus. The drum apparatus includes an integral drum body having a side wall defining a resonant chamber. The integral drum body is formed by an additive manufacturing process or with a volume printing material that shapes the side wall to define an acoustic response of the drum apparatus. The side wall is shaped to define a top perimeter region and a bottom region of the integral drum body. The top perimeter region defines a top opening to the resonant chamber and the bottom region defines a bottom of the resonant chamber, opposite the top perimeter region. The side wall has a thickness or mass distribution controlled by the additive manufacturing process or defined by the volume printing material to modulate the acoustic response of the drum apparatus.

An exemplary snare drum system comprises a shell, a batter head, a snare head, and a set of wires coupled to the snare head. The system comprises a tensioner coupleable to the set of wires of the snare drum. The tensioner comprising a base, a coarse adjuster, and a fine adjuster.

An epoxy coating can be applied to a round surface by keeping the round surface in constant motion, thus defeating the tendency of the epoxy to run off the outer surface of the round object. The process is aided by mechanical equipment that rotates the cylindrical object about its center, while also permitting adjustment of rotational speed.

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.

Provided is a percussion instrument including a substantially cylindrical barrel and a weight fixed to the barrel. More specifically, a plurality of weights 5A to 5D may be provided on the inner circumferential surface of a shell 2 of a drum 1 (a percussion instrument). The weights 5A to 5D may be provided at positions where the weights 5A to 5D have four-fold rotational symmetry in the circumferential direction of the shell 2. The weights 5A to 5D may be each provided between lugs 3 that are provided adjacent to each other on the outer circumferential surface of the shell 2.
