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. [1] 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.
Rototoms can be tuned quickly by rotating the drumhead, which sits in a threaded metal ring. Rotation raises or lowers the tension hoop relative to the rim, which increases or decreases the pitch of the drum by increasing or decreasing the tension of the drumhead.
Drum company Remo has historically offered rototoms in seven diameters: 6 inches (15 cm), 8 inches (20 cm), 10 inches (25 cm), 12 inches (30 cm), 14 inches (36 cm), 16 inches (41 cm), and 18 inches (46 cm). However, as of 2023, Remo only offers rototoms ranging from a 6 to 10 inch diameter as part of a set that includes a mounting rail and stand. All other sizes have been discontinued. Each one is tunable over an octave's range or more, although the company notes that the practical range is approximately a sixth. [2]
Rototoms can replace more specialized drums such as tenor timpani owing to their clear, pitched nature. [3] Jazz, rock and studio performers use rototoms both as a solo voice and as conventional tom-toms; they can be rapidly tuned to produce glissando effects and can be arrayed for a virtual percussion keyboard. For concert and marching band programs, rototoms combine rapid tuning with portability and sound quality, working both as concert tom-toms and as practice timpani. For stage bands and jazz ensembles, drum kits are fitted out with batter heads. When tuned to the mid-range, they have an indefinite pitch with fewer harmonic overtones than conventional tom-toms; tuned to the high range, they produce a sound not unlike timbales.
Rototoms can assist students in ear training and in developing their timpani techniques and— because of their portability, storability and relatively low cost— are often used by professional performers as practice instruments. They are also used as definite-pitched instruments in elementary music programs, such as Orff Schulwerk, where their sound quality, pitch stability and rapid tuning are assets. [4]
English composer Michael Tippett used a total of 38 rototoms— tuned chromatically, spanning across three octaves— in his last large-scale orchestral work, The Rose Lake (1993), based on a lake he spotted suddenly transforming from light green to translucent pink while on holiday in Senegal. [5] In 1979, percussionist William Kraft published Encounters VI, a concertino for rototoms and percussion quartet. [6]
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 player (drummer) typically holds a pair of matching drumsticks, one in each hand, and uses their feet to operate a foot-controlled hi-hat and bass drum pedal.
A percussion instrument is a musical instrument that is sounded by being struck or scraped by a beater including attached or enclosed beaters or rattles struck, scraped or rubbed by hand or struck against another similar instrument. Excluding zoomusicological instruments and the human voice, the percussion family is believed to include the oldest musical instruments. In spite of being a very common term to designate instruments, and to relate them to their players, the percussionists, percussion is not a systematic classificatory category of instruments, as described by the scientific field of organology. It is shown below that percussion instruments may belong to the organological classes of ideophone, membranophone, aerophone and cordophone.
The snare 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.
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.
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.
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 boobam is a percussion instrument of the membranophone family consisting of an array of tubes with membranes stretched on one end, the other end open. The tuning depends partly on the tension on the membrane and partly on the length of the tube.
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.
The davul, dhol, tapan, atabal or tabl is a large double-headed drum that is played with mallets. It has many names depending on the country and region. These drums are commonly used in the music of the Middle East and the Balkans. These drums have both a deep bass sound and a thin treble sound due to their construction and playing style, where different heads and sticks are used to produce different sounds on the same drum.
A tabor, tabret (Welsh: Tabwrdd), Tambour De Provence, or Tambourin (Provencal) is a portable snare drum typically played either with one hand or with two drumsticks. The word "tabor" is simply an English variant of a Latin-derived word meaning "drum"—cf. French: tambour, Italian: tamburo It has been used in the military as a marching instrument, and has been used as accompaniment in parades and processions.
Orchestral percussion refers to the various percussion instruments used in an orchestral setting. It may also refer to the act of playing such instruments in an orchestral style. Many music schools and conservatories offer training for musicians interested in developing their skills as orchestral percussionists. Typically, an orchestral percussionist does not specialize in one particular instrument. Although there is no exhaustive list of all instruments that an orchestral percussionist must be able to play, there are particular instruments that are frequently used in the orchestral repertoire. This includes timpani, snare drum, bass drum, xylophone, glockenspiel, triangle, and tambourine.
A gong bass drum is a musical instrument in the percussion family. It is a type of drum that uses a single large drumhead in order to create a loud, resonant sound when struck. The head can be tuned as loose as possible to avoid any sense of pitch in the sound, or tensioned more tightly to produce timpani-like tones.
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.
A pitched percussion instrument is a percussion instrument used to produce musical notes of one or more pitches, as opposed to an unpitched percussion instrument which is used to produce sounds of indefinite pitch.
This is a partitioned list of percussion instruments showing their usage as tuned or untuned. See pitched percussion instrument for discussion of the differences between tuned and untuned percussion. The term pitched percussion is now preferred to the traditional term tuned percussion:
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.
The flapamba is a musical instrument in the percussion family. It consists of tuned wooden bars pinched on one side over the node and mounted over resonator boxes. Sliding the bars slightly forward or backward affects their tuning. Unlike the marimba or xylophone, the sound is not as focused tonally. It is a bit more percussive, sounding closer to tuned log drums.
Drum tuning is the process of adjusting the frequency or pitch of a drum. Although most drums are unpitched instruments, they still have a fundamental pitch and overtones. Drums require tuning for a variety of reasons: to sound good together as a kit, to sound pleasing as an individual drum, to achieve the desired amount of ringing and resonance, and to produce the sound that fits the music. Some drums such as timpani and rototoms are tuned to a definite pitch. Drums are tuned by tightening or loosening the tension rods or ropes, which control the tension on the drumhead. Additional techniques such as muffling may also be used to affect resonance.
