Instruments of music
Instrumental music is not considered an independent art from vocal music. Yet many instruments were fully described by early writers, and their use in folk, art, religious, and military music pointed out. The most favoured instrument of ancient Middle Eastern civilization, the harp, was gradually overshadowed by both long- and short-necked lutes.
Percussion instruments
Among idiophones (instruments the hard bodies of which vibrate to produce sound) commonly used are the qaḍīb (“percussion stick”), the zil and sunūj (“cymbals”), and the kāṣāt, or small finger cymbals. Membranophones, or vibrating membrane instruments, include a variety of tambourines, or frame drums, which all fall under the generic name duff. These include the North African ghirbāl and bendīr, instruments that have a number of “snares” across the skin and are used for folk dances; and the dāʾirah, or ṭar, with jingling plates or rings set in the frame. The dāʾirah and the vase-shaped drum darabukka (in Iran, z̄arb) are used in folk and art music, and the small kettledrums naqqārah and nuqayrat are used in art music and in military music (such as janissary music, the Turkish ensemble adopted by European military musicians). The large two-headed cylindrical drum, the ṭabl (Turkish davul), is generally played with the oboe-like zornā or gayta in processions and open-air ceremonies.
Wind instruments
Classed with the zornā and gayta as aerophones, or wind instruments, are the būq, or horn, the nafīr, or long trumpet, and a variety of flutes called nāy or shabbābah. Clarinetlike (single-reed) double-piped instruments such as the dunay, zammārah, and urghūl are used in folk events and open-air ceremonies.
Stringed instruments
Chordophones, or stringed instruments, constitute the most important family. The favourite instrument of Islamic classical music is the ʿūd, a short-necked lute, with a bowl-like wooden body, a backward-slanting pegbox, and usually four to six courses of strings, that resembles the Western lute, which derived from the ʿūd. In addition to holding musical supremacy, it was important in medieval theoretical and cosmological speculations. It has two derivatives in North Africa, the kuwītra and the gunbrī. The long-necked lutes favoured in Turkey, Iran, and the countries eastward include the ṭunbūr, tār, and setār. Another plucked instrument is the qānūn, or trapezoid-shaped psaltery, played at least from early medieval times. The trapezoidal dulcimer, or sanṭūr, the strings of which are struck with two thin sticks, is widespread and is especially prominent in Persian art music. Bowed lutes, or fiddles, include the rabāb, used by epic singers and beggars, and the kamān, or kamanjā, a hemispherically-shaped fiddle the body of which, like that of the rabāb, is pierced by the length of wood forming the neck (such instruments are known as spike fiddles). The violin, played either on the knee like the kamanjā, or beneath the collarbone, is also common.
