The instrument differs slightly in different regions. The Kazakh dombyra has frets and is played by strumming with the hand or plucking each string individually, with an occasional tap on the main surface of the instrument. While the strings are traditionally made of sinew, modern dombras are usually produced using nylon strings. One of the greatest dombra players was the Kazakh folk musician and composer Kurmangazy Sagyrbayuly, who had a major influence on the development of Kazakh musical culture, including music for the dombra; his musical composition "Adai" is popular in Kazakhstan and abroad.
