The keleli is a lute of the Teda people of Tibesti, Republic of Chad. [1] [2]
The instrument consists of a round bowl covered with camel, goat or zebra-hide soundboard, and a neck to support the strings. [1] [2]
The instrument is built by individuals for themselves. [2] Children lean to play by imitating adults. [2]
The keleli is a half-spike lute, in which the end of the neck pokes out though the soundboard, [1] as on a xalam. This is one of two styles common to the spike lutes. The other common style is a full spike lute, in which the neck of the instrument goes through two opposite sides of a bowl-shaped soundbox as on a gurmi. [3]
The lute has round soundbox, about 20 inches across, made from a gourd, carved from wood or fashioned from an enamel bowl or metal bowl. [1] The skin soundboard is placed raw over the bowl's opening and tied underneath with thongs. [2] When it dries, it tightens, becoming resonant like a drumhead. [2] The died hide is shaved with a knife. [2]
It is strung with two or three strings, traditionally, strings made from goat sinew. [1] Today nylon strings are common. [1] The bridge is a length of a stick laid on the soundboard next to a soundhole. [1] The strings coming from the neck pass over it and down through the soundhole into the bowl, to attach to the butt of the neck. [1] The soundhole is about 30mm tall by 50mm wide. [2]
Strings are tied to tuning rings or straps on the neck, rather than using tuning pegs; [1] the system is ancient, the tradition found as far back as Ancient Egypt. Another trait similar to ancient Egypt is the manner in which the neck goes though a hole in the top of the soundboard and run under it until it reaches another hole, thus being threaded into the soundboard. [1] [2] The end of the stick is exposed at a soundhole near the bowls end. [1]
For a two string instrument, the strings are tuned about a third apart. [2] For a three-string instrument, the third string (chanterelle) is turned an octave above the lowest-note string. [2]
The instrument is played by men and boys, starting as children until they reach their mid-forties. [2] There is a set repertoire of music for the instrument, usually only instrumental, but sometimes with "bourdon-like humming in the letter zzz, or a low, quiet whispering of a text." [2]
The keleli is very similar to another Teda lute called the kiiki. [4] The main difference between the two is that the kiiki is strung with only one string (made of 12 srands of horsehair) and is bowed instead of plucked. [4] Each lute, plucked and bowed, may be converted to the other by changing strings. [4]
A mandolin is a stringed musical instrument in the lute family and is generally plucked with a pick. It most commonly has four courses of doubled strings tuned in unison, thus giving a total of eight strings. A variety of string types are used, with steel strings being the most common and usually the least expensive. The courses are typically tuned in an interval of perfect fifths, with the same tuning as a violin. Also, like the violin, it is the soprano member of a family that includes the mandola, octave mandolin, mandocello and mandobass.
String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner.
The crwth, also called a crowd or rote or crotta, is a bowed lyre, a type of stringed instrument, associated particularly with Welsh music, now archaic but once widely played in Europe. Four historical examples have survived and are to be found in St Fagans National Museum of History (Cardiff); National Library of Wales (Aberystwyth); Warrington Museum & Art Gallery; and the Museum of Fine Arts, Boston (US).
The kobza, also called bandurka is a Ukrainian folk music instrument of the lute family, a relative of the Central European mandora. The term kobza however, has also been applied to a number of other Eastern European instruments distinct from the Ukrainian kobza.
Ektara is a one-stringed musical instrument used in the traditional music of South Asia, and used in modern-day music of Bangladesh, India, and Pakistan.
The yueqin, also called a moon lute or moon guitar, is a traditional Chinese string instrument. It is a lute with a round, hollow soundboard, a short fretted neck, and usually four strings. It is an important instrument in the Peking opera orchestra, often taking the role of main melodic instrument in lieu of the bowed string section.
The bowed psaltery is a type of psaltery or zither that is played with a bow. In contrast with the centuries-old plucked psaltery, the bowed psaltery appears to be a 20th-century invention.
The citole was a string musical instrument, closely associated with the medieval fiddles and commonly used from 1200–1350. It was known by other names in various languages: cedra, cetera, cetola, cetula, cistola, citola, citula, citera, chytara, cistole, cithar, cuitole, cythera, cythol, cytiole, cytolys, gytolle, sitole, sytholle, sytole, and zitol. Like the modern guitar, it was manipulated at the neck to get different notes, and picked or strummed with a plectrum. Although it was largely out of use by the late 14th century, the Italians "re-introduced it in modified form" in the 16th century as the cetra, and it may have influenced the development of the guitar as well. It was also a pioneering instrument in England, introducing the populace to necked, plucked instruments, giving people the concepts needed to quickly switch to the newly arriving lutes and gitterns. Two possible descendant instrument are the Portuguese guitar and the Corsican Cetera, both types of cittern.
The tro is Cambodia's traditional spike fiddles, bowed string instruments that are held and played vertically. Spike fiddles have a handle that passes through the resonator, often forming a spike, on the bottom side where it emerges. The family is similar or distantly related to the Chinese erhu or huqin. The instruments have a soundbox at the bottom of the stick, covered with leather or snake skin. Strings run from pegs at the top of the stick and secured at the bottom, running across the soundbox. The larger the soundbox, the lower the pitch range. Instruments in this family include the two-stringed tro ou, tro sau thom, tro sau toch and tro che, as well as the three-stringed tro Khmer spike fiddle. The two-stringed tros are tuned in a fifth, while the three-stringed tro Khmer is tuned in fourths. The tros, with the exception of the tro Khmer, are strung so that the bowstring is permanently placed between the two stings. When the musician plays, the placement of the bow causes the strings to be played at once, one from below and one from above. In contrast, western fiddles are played with the bow pushing on each string from the outside, as is also the case with the tro khmer.
Plucked string instruments are a subcategory of string instruments that are played by plucking the strings. Plucking is a way of pulling and releasing the string in such a way as to give it an impulse that causes the string to vibrate. Plucking can be done with either a finger or a plectrum.
A qanbūs is a short-necked lute that originated in Yemen and spread throughout the Arabian peninsula. Sachs considered that it derived its name from the Turkic komuz, but it is more comparable to the oud. The instrument was related to or a descendant of the barbat, a (possibly) skin-topped lute from Central Asia. The qanbūs has 6 or 7 nylon strings that are plucked with a plectrum to generate sound. Unlike many other lute-family instruments, the gambus has no frets. Its popularity declined in Yemen during the early 20th century reign of Imam Yahya; by the beginning of the 21st century, the oud had replaced the qanbūs as the instrument of choice for Middle-Eastern lutenists.
The mandore is a musical instrument, a small member of the lute family, teardrop shaped, with four to six courses of gut strings and pitched in the treble range. Considered a French instrument, with much of the surviving music coming from France, it was used across "Northern Europe" including Germany and Scotland. Although it went out of style, the French instrument has been revived for use in classical music. The instrument's most commonly played relatives today are members of the mandolin family and the bandurria.
The Byzantine lyra or lira was a medieval bowed string musical instrument in the Byzantine Empire. In its popular form, the lyra was a pear-shaped instrument with three to five strings, held upright and played by stopping the strings from the side with fingernails. The first known depiction of the instrument is on a Byzantine ivory casket, preserved in the Bargello in Florence. Versions of the Byzantine lyra are still played throughout the former lands of the Byzantine Empire: Greece, Crete, Albania, Montenegro, Serbia, Bulgaria, North Macedonia, Croatia, Italy and Armenia.
The endingidi is a type of bowed string instrument native to Uganda. The endingidi has one string, extending from the neck to a cylindrical sound-box or resonator made of wood or cow horn. A piece of hide is stretched over the top of the cylinder and is fixed to the sound-box with wooden pegs, thorny spines or nowadays also with metal nails. The hide used is usually that of the monitor lizard but also of young goats and sheep or even of the python. The hide is soaked in water for a whole day before being stretched over the sound-box. The neck consists of a straight wooden stick inserted through the walls of the sound-box at about 2 to 3 cm from the top. At the top of the neck a hole is bored at 4 to 6 cm from the end into which a tuning pin is inserted vertically. The string is secured to this pin in such a way that the string can be wound round the pin in a similar way as with a violin. This allows the string to be tightened, so tuning the instrument. The string runs across the sound-box via a bridge and is fixed to the other end of the neck. The string is made of fibre or animal sinew, but nowadays it is more often of nylon. The arched bow consists of a thin flexible twig, to which a string is attached, usually of the same material as the string of the instrument itself. To give the bow more grip on the string of the instrument, resin is rubbed into the bow string. The resin is often attached to the side of the sound-box so the player can easily rub resin on the bow as he plays.
The omubanda is a type of end-blown flute native to Uganda.
The rawap or rubab is an Eastern Iranian fretted plucked long-necked stringed instrument also used in folk music by residents of the Uyghur autonomous region of Xinjiang, Western China. The history of the instrument dates back to the Ancient Iran including modern Tajikistan and spreading in the 14th century to Turkic cultures including southern Xinjiang. It is an instrument of the Tajiks also used in Uzbekistan. It's particularly associated with Tajik music and culture including Tajiks of Bukhara and Samarkand.
The satar is a traditional Uyghur long-necked bowed lute. It is used by Uyghur people in Xinjiang, western China, and is an important instrument to play maqams.
The garaya or komo is an oval-bodied, two-string spike lute from Niger and Northern Nigeria.
The gurmi is a two or three-stringed lute of the Hausa people of northern Nigeria. May also be called gurumi or kumbo. In looking at the two-finger playing style used by musicians who play the gumbri, researchers have listed it as a possible relative to the banjo. Researchers have talked about the gurmi and gurumi as if these are two different but similar instruments.
Molo is the name given to a lute by the Hausa people of Niger and northern Nigeria and the Songhay people of Niger.
