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 percussion mallet, to produce sound. There is usually a resonant head on the underside of the drum. 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.
A drum kit is a collection of drums, cymbals, and sometimes other auxiliary percussion instruments set up to be played by one person. The drummer typically holds a pair of matching drumsticks, and uses their feet to operate hi-hat and bass drum pedals.
The snare drum is a percussion instrument that produces a sharp staccato sound when the head is struck with a drum stick, due to the use of a series of stiff wires held under tension against the lower skin. Snare drums are often used in orchestras, concert bands, marching bands, parades, drumlines, drum corps, and more. It is one of the central pieces in a drum set, a collection of percussion instruments designed to be played by a seated drummer and used in many genres of music. Because basic rhythms are very easy to learn to play on a snare drum even for children, the instrument is also suitable for the music education for young children and a rhythm band.
The bass drum is a large drum that produces a note of low definite or indefinite pitch. The instrument is typically cylindrical, with the drum's diameter much greater than the drum's depth, with a struck head at both ends of the cylinder. The heads may be made of calfskin or plastic and 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 does not dictate the volume produced by the drum. The pitch and the sound can vary much with different sizes, but the size is also chosen based on convenience and aesthetics. 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.
Timpani or kettledrums are musical instruments in the percussion family. A type of drum categorised as a hemispherical drum, they consist of a membrane called a head stretched over a large bowl traditionally made of copper. Thus timpani are an example of kettle drums, also known as vessel drums and semispherical drums, whose body is similar to a section of a sphere whose cut conforms the head. Most modern timpani are pedal timpani and can be tuned quickly and accurately to specific pitches by skilled players through the use of a movable foot-pedal. They are played by striking the head with a specialized drum stick called a timpani stick or timpani mallet. Timpani evolved from military drums to become a staple of the classical orchestra by the last third of the 18th century. Today, they are used in many types of ensembles, including concert bands, marching bands, orchestras, and even in some rock bands.
In music, inharmonicity is the degree to which the frequencies of overtones depart from whole multiples of the fundamental frequency.
A drumhead or drum skin is a membrane stretched over one or both of the open ends of a drum. The drumhead is struck with sticks, mallets, or hands, so that it vibrates and the sound resonates through the drum.
A djembe or jembe is a rope-tuned skin-covered goblet drum played with bare hands, originally from West Africa. According to the Bambara people in Mali, the name of the djembe comes from the saying "Anke djé, anke bé" which translates to "everyone gather together in peace" and defines the drum's purpose. In the Bambara language, "djé" is the verb for "gather" and "bé" translates as "peace."
The conga, also known as tumbadora, is a tall, narrow, single-headed drum from Cuba. Congas are staved like barrels and classified into three types: quinto, tres dos or tres golpes (middle), and tumba or salidor (lowest). Congas were originally used in Afro-Cuban music genres such as conga and rumba, where each drummer would play a single drum. Following numerous innovations in conga drumming and construction during the mid-20th century, as well as its internationalization, it became increasingly common for drummers to play two or three drums. Congas have become a popular instrument in many forms of Latin music such as son, descarga, Afro-Cuban jazz, salsa, songo, merengue and Latin rock.
The rototom is a shell-less drum developed by Al Payson and Michael Colgrass that is able to change pitch by rotating its drumhead around a threaded metal ring. Unlike many types of drums, rototoms are designed to have a variable definite pitch leading composers to write specific notes for them as pitched percussion instruments. They are also often used to extend the tom range of a standard drum kit.
Marching percussion instruments are percussion instruments specially designed to be played while moving. This is achieved by attaching the drum(s) to a special harness worn by the drummer, although not all marching bands use such harnesses and instead use traditional baldrics to sling their drums.
A tenor drum is a membranophone without a snare. There are several types of tenor drums.
The Basel drum is a two-headed rope-tension drum. It takes its name from its origin in Basel. This percussion instrument is best known from the Carnival of Basel, where it is played by more than 2000 drummers. They are called Tambouren in Swiss German or Tambourins in French. There is no typical number of players for marching-bands including this instrument. Anything between three and fifty drummers may be seen in such a formation.
Remo Inc. is an American musical instruments manufacturing company based in Valencia, California, and founded by Remo Belli in 1957. Products manufactured include drum kits, drumheads, drums, and hardware, and various percussion instruments.
Jean-Paul Gaster is an American musician who is the drummer for the rock band Clutch.
Drum hardware is the set of parts of a drum or drum kit that are used to tension, position, and otherwise support the instruments themselves.
A stoptail bridge used on a solid body electric guitar or archtop guitar is a specialized kind of fixed hard-tail bridge. Hard-tail bridged guitars use different bridges from those guitars fitted with vibrato systems.
A tom drum is a cylindrical drum with no snares, named from the Anglo-Indian and Sinhala language. It was added to the drum kit in the early part of the 20th century. Most toms range in size between 6 and 20 inches in diameter, though floor toms can go as large as 24 inches (61 cm).
The modern timpani evolved in the 18th and 19th centuries from the simple 12th-century membranophone of the Naker to a complex instrument, consisting of a suspended kettle with a foot-operated clutch, capable of rapid tuning. The technological evolution of the instrument led to increased interest in its capabilities and sound among such composers as Joseph Haydn, Ludwig van Beethoven, Robert Schumann, and Hector Berlioz.
An unpitched percussion instrument is a percussion instrument played in such a way as to produce sounds of indeterminate pitch, or an instrument normally played in this fashion.
