Bass drum

A bass drum is a large drum that produces a note of low definite or indefinite pitch.

Bass drums are percussion instruments and vary in size and are used in several musical genres. Three major types of bass drums can be distinguished.

Description

A bass drum is typically cylindrical with the diameter much greater than the height. There is normally a struck head at both ends of the cylinder. The heads may be made of calf skin or plastic. There is normally a means of adjusting the tension either by threaded taps or by strings. Bass drums are built in a variety of sizes, but size has little to do with the volume produced by the drum. The size chosen being based on convenience and aesthetics.

Kick

A kick is a physical strike using the foot, leg, or knee (the latter is also known as a knee strike). This type of attack is used frequently by hooved animals as well as humans in the context of stand-up fighting. Kicks play a significant role in many forms of martial arts, such as savate, Combat Hopak, taekwondo, sikaran, karate, Pankration, Kung fu, Vovinam, kickboxing, Muay Thai, capoeira, silat, and kalaripayattu.

Kicking is also prominent from its use in many sports, especially those called football. The best known of these sports is association football, also known as soccer.

History

The English verb to kick appears only in the late 14th century, apparently as a loan from Old Norse, originally in the sense of a hooved animal delivering strikes with his hind legs; the oldest use is Biblical.

Kicks as an act of human aggression have likely existed worldwide since prehistory. However, high kicks, aiming above the waist or to the head appear to have originated from Asian martial arts. Such kicks were introduced to the west in the 19th century with early hybrid martial arts inspired by Asian styles such as Bartitsu and Savate. Practice of high kicks became more universal in the second half of the 20th century with the more widespread development of hybrid styles such as kickboxing and eventually mixed martial arts.

Drum

The drum is a member of the percussion group of musical instruments. In the Hornbostel-Sachs classification system, it is a membranophone. Drums consist of at least one membrane, called a drumhead or drum skin, that is stretched over a shell and struck, either directly with the player's hands, or with a drum stick, to produce sound. There is usually a resonance head on the underside of the drum, typically tuned to a slightly lower pitch than the top drumhead. Other techniques have been used to cause drums to make sound, such as the thumb roll. Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years.

Drums may be played individually, with the player using a single drum, and some drums such as the djembe are almost always played in this way. Others are normally played in a set of two or more, all played by the one player, such as bongo drums and timpani. A number of different drums together with cymbals form the basic modern drum kit.
