The rebab (Arabic الربابة or ربابة - "a bowed (instrument)"), also rebap, rabab, rebeb, rababah, or al-rababa) is a type of string instrument so named no later than the 8th century and spread via Islamic trading routes over much of North Africa, the Middle East, parts of Europe, and the Far East. The bowed variety often has a spike at the bottom to rest on the ground, and is thus called a spike fiddle in certain areas, but plucked versions like the kabuli rebab (sometimes referred to as the robab or rubab) also exist. Furthermore, besides the spike fiddle variant, there also exists a variant with a pear-shaped body, quite similar to the Byzantine lyra and the Cretan lyra. This latter variant travelled to western Europe in the 11th century, and became the rebec.
This article will only concentrate on the spike-fiddle rebab, which usually consists of a small, usually rounded body, the front of which is covered in a membrane such as parchment or sheepskin and has a long neck attached. There is a long thin neck with a pegbox at the end and there are one, two or three strings. There is no fingerboard. The instrument is held upright, either resting on the lap or on the floor. The bow is usually more curved than that of the violin.
The rebab, though valued for its voice-like tone, has a very limited range (little over an octave), and was gradually replaced throughout much of the Arab world by the violin and kemenche. It is related to the Iraqi instrument the Joza, which has four strings.
The rebab is used in a wide variety of musical ensembles and genres, corresponding with its wide distribution, and is built and played somewhat differently in different areas. In Southeast Asia, the rebab is a large instrument with a range similar to the viola da gamba, whereas versions of the instrument further west tend to be smaller and higher-pitched. The body varies from being ornately carved, as in Java, to simpler models such as the 2-string Egyptian "fiddle of the Nile" may have a body made of half a coconut shell. The more sophisticated versions have a metal soundbox and the front may be half-covered with beaten copper, and half with cowskin.
Arabia, Persia and the Ottomans 
The rebab was heavily used, and continues to be used, in Arabic bedouin music as well Iraqi . There is also a bowed instrument in Persian music named Kamanche which has similar shape and structure. The Rebab is also played in Afghanistan and Pakistan, most likely tracing its origin to Iraq and Arabia due to the traces found in Nassirya, Iraq and some parts of Saudi Arabia and UAE.
Asian heartland 
The spike fiddle variants are very commonly used by many East and Central Asian ethnic groups and their diaspora around the world, such as the Huqin variety used by most ethnic groups of China, the morin khuur of Mongolia, the Byzaanchy of Tuva, the Kokyū of Japan, Haegeum of Korea, kyl kiak of Kyrgyzstan, Saw sam sai of Thailand and many others. These are generally used in playing traditional folk tunes, but have also become popular in arrangements of contemporary music, including such genres as classical, jazz, and rock.
Malay Archipelago 
In the Indonesian gamelan the rebab is an essential elaborating instrument, ornamenting the basic melody. A two-string bowed lute consisting of a wooden body, traditionally though now rarely a single coconut shell, covered with very fine stretched skin. Two brass strings are tuned a fifth apart and the horse hair bow is tied loosely (unlike modern Western stringed instruments) with the proper tension controlled by the players bow hand, contributing to the difficult technique. There are typically two per ensemble, one for pelog and one for slendro, never played together.
The rebab does not have to conform exactly to the scale of the other gamelan instruments and can be played in relatively free time, finishing its phrases after the beat of the gong ageng (the big gong that "rules" the ensemble, see: colotomy). The rebab also frequently plays the buka when it is part of the ensemble.
In the eastern Malaysian states of Kelantan and Terengganu, the Rebab is used in a healing ritual called "Main Puteri". The musician healer is sometimes taken to hospitals in cases where doctors are unable to heal ailing patients.
