Which woodwind instrument was proclaimed by UNESCO as a Masterpiece of the Intangible Heritage of Humanity?

The duduk is an ancient Armenian double-reed woodwind instrument made of apricot wood. It is indigenous to Armenia. Variations of the Armenian duduk appear throughout the Caucasus and the Middle East, including Azerbaijan, Georgia, Russia, Turkey, and Iran. It is commonly played in pairs: while the first player plays the melody, the second plays a steady drone called dum, and the sound of the two instruments together creates a richer, more haunting sound.

UNESCO proclaimed the Armenian duduk and its music as a Masterpiece of the Intangible Heritage of Humanity in 2005 and inscribed it in 2008. Duduk music has been used in a number of films, most notably in The Russia House and Gladiator.
