Sinan Ayyildiz studied at the Turkish State Music Conservatory in Istanbul. He plays a long-necked (sometimes double-necked) Turkish stringed instrument called the bağlama (pronounced BAH-le-mah) in a style called şelpe (pronounced SHEL-pee), which involves an overhand 8-finger tapping technique. His repertoire includes Turkish, Persian, Armenian, Bulgarian, and Western Classical music. Sinan is playing on the right side of the screen in the above video. Check out these videos of him on Turkish national television(with and without his band Etnika).
