Qanun or Kanun may refer to:
The kanun, ganoun or kanoon (Arabic: قانون, qānūn, pl. qawānīn; Greek: κανονάκι, kanonaki; Armenian: քանոն, k’anon; Persian: قانون, qānūn; Azerbaijani: qanun; Turkish: kanun) is a string instrument played in much of the Middle East, Central Asia, and southeastern Europe. The name derives from the Arabic word kānun, which means "rule, norm, principle" itself from ancient Greek 'κανών' rule. Its traditional music is based on maqamat. It is a type of large zither with a narrow trapezoidal soundboard. Nylon or PVC strings are stretched over a single bridge poised on fish-skins on one end, attached to tuning pegs at the other end.
Qanun used in Turkey have 26 courses of strings, with three strings per course. It is played on the lap by plucking the strings with two tortoise-shell picks, one in each hand, or by the fingernails, and has a range of three and a half octaves, from A2 to E6. The dimensions of Turkish kanuns are typically 95 to 100 cm (37-39") long, 38 to 40 cm (15-16") wide and 4 to 6 cm (1.5-2.3") high. The instrument also has special latches for each course, called mandals. These small levers, which can be raised or lowered quickly by the performer while the instrument is being played, serve to change the pitch of a particular course slightly by altering the string lengths.
Qanun is an Arabic word (Arabic: قانون) derived from the Greek κανών (kanōn, the root for the modern English word "canon"). It can refer to laws promulgated by Muslim sovereigns, in particular the Ottoman Sultans, in contrast to shari'a, the body of law elaborated by Muslim jurists. The 10th sultan of the Ottoman Empire, Suleiman was known in the Ottoman Empire as Suleiman Kanuni ("the Lawgiver"), due to his code of laws.
After the fall of the Abbasids in 1258, a practice known to the Turks and Mongols transformed itself into Qanun, which gave power to caliphs, governors, and sultans alike to "make their own regulations for activities not addressed by the sharia." This became increasingly important as the Middle East started to modernize, thus running into the problems of a modern state, which were not covered by Shariah. The Qanun began to unfold as early as Umar I (586-644 CE). Many of the regulations covered by Qanun were based on financial matters or tax systems adapted through the law and regulations of those territories Islam conquered. Qanun in Arabic means law or rules.
