The main instrument in the piece that sounds like a wind instrument (like a flute) is a 3000 yr old Armenian instrument called Duduk (pronounced DUDHOOK). The song is called Tears in Armenia. It was composed to mark the 100 yrs of Genocide that Armenians had to face from the Turks in early 1900s. Duduk is made of  seasoned apricot stem and bones. It has 2 parts to it. This is the only instrument that sounds like a man’s husky voice
