The instruments used are a mixture of Anatolian and Central Asian instruments (the saz, the bağlama, the kemence), other Middle Eastern instruments (the ud, the tanbur, the kanun, the ney), and—later in the tradition—Western instruments (the violin and the piano). Because of a geographic and cultural divide between the capital and other areas, two broadly distinct styles of music arose in the Ottoman Empire: Ottoman classical music, and folk music. In the provinces, several different kinds of folk music were created. The most dominant regions with their distinguished musical styles are: Balkan-Thracian Türküs, North-Eastern (Laz) Türküs, Aegean Türküs, Central Anatolian Türküs, Eastern Anatolian Türküs, and Caucasian Türküs. Some of the distinctive styles were: Janissary Music, Roma music, Belly dance, Turkish folk music.
