Barbat (lute) in the context of "Luthier"

The oud (/uːd/ OOD; Arabic: عُود, romanized: ʿūd, pronounced [ʕuːd]) is a Middle Eastern short-neck lute-type, pear-shaped, fretless stringed instrument (a chordophone in the Hornbostel–Sachs classification of instruments), usually with 11 strings grouped in six courses, but some models have five or seven courses, with 10 or 13 strings respectively.

The oud is similar to other types of lute, and to Western lutes which developed out of the Medieval Islamic oud. Similar instruments have been used in the Middle East, some predating Islam, such as the barbat from Persia. Different versions of the oud are used in Arabia, Turkey, and other Middle Eastern and Balkan regions. The oud, as a fundamental difference with the western lute, has no frets and a smaller neck. It is the direct successor of the Persian barbat lute. The oldest surviving oud is thought to be in Brussels, at the Museum of Musical Instruments.

A qanbūs (Arabic: قنبوس) 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.

Yemen migration saw the instrument spread to different parts of the Indian Ocean. In Muslim Southeast Asia (especially Indonesia, Malaysia and Brunei), called the gambus, it sparked a whole musical genre of its own. Nowadays it is played in the traditional dance of Zapin and other genres, such as the Malay ghazal and an ensemble known as kumpulan gambus ("gambus group"). In the Comoros it is known as gabusi, and in Zanzibar as gabbus.
