A reverberating percussion instrument has a resonating chamber of a completely smoothly contoured configuration to facilitate generation of long-duration pitched reverberations, and a plurality of hollow and substantially mutually parallel vibratable tubes of different lengths, each of which being suspended from an element of the resonating chamber by a tensioned filament at each longitudinal end thereof. Reverberated and resonating musical sounds are directed forwardly from the resonating chamber in response to selective vibration of one or more of the tubes.

An acoustic variable porting system includes an acoustic element and an acoustic variable porting element forming a port into the acoustic element. The acoustic variable porting element is adjustable between at least an open position, in which the port is generally open, and a closed position, in which the port is generally closed. The acoustic element may be at least one of: a sub-kick, a ported drum, and a speaker.

A sound damping device includes a sound damper and a support member. The sound damper includes a contact surface configured to contact a vibration member and includes a through-hole having a first opening formed on the contact surface. The support member is coupled to the sound damper to support the sound damper and cause the vibration member and the contact surface to come into contact with each other. The support member includes an air hole that is connected to the through-hole of the sound damper and that penetrates through the support member.

The acoustic variable porting element is adjustable between at least an open position, in which the port is generally open, and a closed position, in which the port is generally closed. The acoustic element may be at least one of: a sub-kick, a ported drum, and a speaker.

A drum and pitch adjustment device for a drum includes a drum with a sound producing membrane, a device for applying pressure to the sound producing membrane, and a cable configured to the device for applying and releasing pressure to the sound producing membrane, changing the pitch of the drum, but goes back to the drum's original pitch when absent this force. A hand operated lever, located on the side of the drum, operates the cable which makes the pressure device push up against the sound producing membrane and changing it's pitch. Absent this force, the drum goes back to its original pitch, which creates different tonal variety when played in real-time.

A first vessel provided in spaced nested relation to and at least partially around a second vessel or member, the first vessel having a bottom section coupled to a sidewall to form a liquid receiving receptacle open at an upper end of the sidewall. Further provided is liquid in the liquid receiving receptacle. The second vessel or member is moveable relative to the first vessel to displace and/or replace the liquid in the first vessel such that the first vessel can produce different pitches and/or tones as or after the liquid is displaced and/or replaced and the first vessel is struck, rubbed or otherwise vibrated.

A musical instrument includes: a vibrating member configured to be vibrated by a playing operation; an adjusting mechanism configured to perform physical adjustment to change a vibration manner of the vibrating member in playing; a detector configured to detect an adjustment state of the adjusting mechanism; a musical-sound generator configured to generate musical sound based on the playing operation; and a controller configured to control a manner of generation of the musical sound by the musical-sound generator, based on the adjustment state detected by the detector.

An instrument modeled after a hi hat hi-hat consisting of wood, metal (or other material) and linked material, creating a complex sound effect when closed together, and an 808 (i.e. Roland 808 or similar) snare drum sound when struck with drumstick is disclosed. This invention allows drummers to create complex sounds using the hi-hat pedal (or other mounting device), to lower the Top Hi-hat toward the Bottom Hi-hat and cause the linked material to connect with the bottom hi-hat. The claimed device also replaces the standard electronic pad (such as but not limited to the Roland SPDS sampler pad) that recreated the famous 808 (i.e. Roland 808 or similar) handclap sound. Variations of the invention is meant to be used either alongside the traditional metal hi-hat or in lieu of the traditional metal hi-hat.

The disclosure herein includes a drum coupling assembly, which drum coupling assembly may include: a drum having a drum hoop and a drumhead; a first clamp coupled to the drum hoop; a second clamp coupled to the drum hoop; and an elastic cord coupled to the first clamp and the second clamp, an elastic cord, wherein at least a portion of the elastic cord extends between the first clamp and the second clamp, and wherein at least a portion of the elastic cord is disposed between an edge of the drum hoop and above the drumhead.
