Central to the Thracian folklore area is the vast Thracian valley. It is enclosed by the Balkan mountains, Pirin, Rila, and the Rhodopes and stretches all the way to the Black Sea coast. It incorporates villages on the northern slopes of the Rhodopes, east of Pazardzhik. Some researchers believe that Thrace is the oldest folklore area in Bulgaria. It is the birthplace of the most ancient culture on the Balkan peninsula, which was created by its first inhabitants, the Thracian people.
The folklore music of Thrace is unbelievably beautiful, expressive and vivacious. Tranquillity and beauty spill out of the Thracian songs and the melodious kavals. This region includes the area of Strandzha.
