Bozlak, which is a form of uzun hava (long tune) in Turkish Folk Music, has been a form of music starting from Central Anatolia and an expression of the cultures of the Yoruk / Turkmen and Avshar tribes which pursue a way of life based on yaylak (summer highland pasture)- and kislak (winter pasture). In terms of meaning, the word ‘bozlak’ has the meanings of to shout, to yell, to cry out, and to burst out. The bursting out of the sorrow, desolation and the outbreak that the Turkmens and Avshars experienced in daily life to the nature caused the emergence of the bozlak culture. Turkmens, Avshars and the Abdals who existed among these tribes have transferred the tradition of bozlak to our day.
