Musical styles, like language patterns and other cultural traits, were influenced by the topography of Pontos. The mountains and rivers of the area impeded communication between Pontian Greek communities and caused them to develop in different ways. Also significant in the shaping of Pontian music was the proximity of various non-Greek peoples on the fringes of the Pontic area. For this reason we see that musical style of the east Pontos has significant differences from that of the west or southwest Pontos. The Pontian music of Kars, for example, shows a clear influence from the music of the Caucasus and elements from other parts of Anatolia. The music and dances of Turks from Black Sea region are very similar to Greek Pontic and some songs and melodies are common. Except for certain laments and ballads, this music is played primarily to be danced to.
