Turkish folk music (Türk Halk Müziği) is the traditional music of Turkish people living in Turkey influenced by the cultures of Anatolia and former territories in Europe and Asia. Its unique structure includes regional differences under one umbrella. It includes popular music from the Ottoman Empire era. After the foundation of the Turkish Republic in 1923, Turkish President Mustafa Kemal Atatürk ordered a wide-scale classification and archiving of samples of Turkish folk music from around the country, which, from 1924 to 1953 collected around 10,000 folk songs. Traditional folk music was combined with Western harmony and musical notation to create a more modern style of popular Turkish music.
