Qanun or Kanun may refer to:
The Kanun is a set of traditional Albanian laws. The Kanun was primarily oral and only in the 20th century was it published in writing. There is only one Kanun since ancient times commonly referred to as the "Kanun of Leke", from which six later variations eventually evolved, categorized according to the area, the personality and their time of origin: Kanun i vjetër (English: Old Kanun), Kanuni i Lekë Dukagjinit (English: The Kanun of Lekë Dukagjini), Kanuni i Çermenikës (English: The Kanun of Çermenikë), Kanuni i Papa Zhulit (English: The Kanun of Pope Julius), Kanuni i Labërisë (English: The Kanun of Labëria) and Kanuni i Skenderbeut (English: Kanun of Skanderbeg) also known as Kanuni i Arbërisë (English: Kanun of Arbëria).
The Kanun of Skanderbeg is the closest in similarity with the Kanun of Lekë Dukagjini, and the latter is usually the most known and is also regarded as a synonym of the word kanun. The Kanun of Lekë Dukagjini was developed by Lekë Dukagjini, who codified the existing customary laws. It has been used mostly in northern and central Albania and surrounding areas formerly in Yugoslavia where there is a large ethnic Albanian population; Montenegro, Kosovo and Macedonia. It was first codified in the 15th century but the use of it has been outspread much earlier in time. It was used under that form until the 20th century, and revived recently after the fall of the communist regime in the early 1990s.
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.
