Byzantine music
Although the region was under the dominion of the Byzantine Empire for many centuries, the Balkan polyphonic traditional music had a different development than medieval Byzantine music. The Balkan tradition was non-institutionalized and has been continually collectively formed, while the Byzantine music was created by individual composers and was institutionalized. The Balkan tradition has been transmitted orally down the generations, and its performers were common people musically illiterate, while the Byzantine music was widely documented, and has been performed by professionals who were trained and educated. The two musical traditions lived side by side for centuries, therefore they would have had a mutual influence on each other. However, it is thought that the interaction between the Albanian polyphonic traditional music and the Byzantine music has been relatively small.
