cane in a duck-bill type assembly. Unlike other double-reed instruments, the reed is quite wide, helping to give the duduk both its unique, mournful sound, as well as its remarkable breathing requirements. The duduk player is called dudukahar (դուդուկահար) in Armenian. The performer uses air stored in their cheeks to keep playing the instrument while they inhale air into their lungs. This "circular" breathing technique is commonly used with all the double-reed instruments in the Middle East. Duduk "is invariably played with the accompaniment of a second dum duduk, which gives the music an energy and tonic atmosphere, changing the scale harmoniously with the principal duduk." History Armenian musicologists cite evidence of the duduk's use as early as 1200 BC, though Western scholars suggest it is 1,500 years old. Variants of the duduk can be found in Armenia and the Caucasus. The history of the Armenian duduk music is dated to the reign of the Armenian king Tigran the Great, who reigned from 95 to 55 B.C. According to ethnomusicologist Dr. Jonathan McCollum, the instrument is depicted in numerous Armenian manuscripts of the Middle Ages, and is "actually the only truly Armenian instrument that's survived through history, and as such is a symbol of Armenian national identity ... The most important quality of the duduk is its ability to express the language dialectic and mood of the Armenian language, which is often the most challenging quality to a duduk player." Balkan duduk While "duduk" most commonly refers to the double reed instrument described on this page, by coincidence there is a different instrument of the same name played in northwestern Bulgaria. This is a blocked-end flute resembling the Serbian frula, known also as kaval or kavalče in a part of Macedonia, and as duduk (дудук) in northwest Bulgaria. Made of maple or other wood, it comes in two sizes: and (duduce). The blocked end is flat. In popular culture The sound of the duduk has become known to wider audiences through its use in popular film soundtracks. Starting with Peter Gabriel's score for Martin Scorsese's The Last Temptation of Christ, the duduk's archaic and mournful sound has been employed in a variety of genres to depict such moods. Djivan Gasparyan played the duduk in Gladiator, Syriana, and Blood Diamond, among others. It was also used extensively in Battlestar Galactica.
