Music of Turkey includes mainly Turkic elements as well as partial influences ranging from Central Asian folk music, Arabic music, Greek music, Ottoman music, Persian music and Balkan music, as well as references to more modern European and American popular music. The roots of traditional music in Turkey span across centuries to a time when the Seljuk Turks migrated to Anatolia and Persia in the 11th century and contains elements of both Turkic and pre-Turkic influences. Much of its modern popular music can trace its roots to the emergence in the early 1930s drive for Westernization.
