A device integrally joined with the ported opening of a musical bass drum resonant drumhead for regulating the amount of vibrating airflow passing through the inside of a bass drumshell and continuing through the ported opening for effectively controlling undesirable higher frequency drum sounds precipitated by the airflow produced upon the striking of the batter head.

A drumstick is integrated with a drum key for ready availability of a drum key in more situations. The drumstick provides an elongated handle for actuating the key while the key's presence does not interfere with the drumstick's natural use. The drumstick may be organically fashioned with a drum key hollowed out from its own material, thereby providing the requisite negative space, or an insert may be positioned within a butt end of the drumstick which presents the negative space of the drum key. Alternately a sleeve may be positioned on the drumstick to accommodate a key insert or an integral key portion.

A tuning system enabled to be installed inside a drum percussion musical instrument is provided comprising a cylindrical drum shell having a batter head at a top, a bottom, and one or more internal tuning assemblies (ITAs) installed within an inner volume of the drum shell. Sound elements created by striking the batter head of the drum includes any one or more of pitch, resonance and amplitude and are altered, thereby providing tuning of the drum via manipulation of the one or more of the ITAs.

A drum includes a low volume drum head, a pellet chamber, and a magnetic choke. The pellet chamber is located beneath the low volume drum head. The pellet chamber is configured to hold a plurality of pellets, and the pellet chamber defines a plurality of apertures in a wall of the pellet chamber. The magnetic choke carries at least one magnet. The magnetic choke is configured to move relative to the pellet chamber so as to adjust a magnetic force imparted on the pellet chamber.

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.
