Kir Stefan the Serb

Kir Stefan the Serb (Serbian Cyrillic: Кир Стефан Србин/Kir Stefan Srbin; second half of the 14th and 15th century) was a Serbian monk, protopsaltos, musicologist, choirmaster. More importantly, composers of the chants developed within the sphere of the activities of the Byzantine church in the Serbian state. Together with (but independently from) Isaiah the Serb and Nikola the Serb he followed faithfully the Byzantine musical traditions, writing in the late kalophonic style of the 14th and 15th centuries. With his distinctive compositional style, he is one of the earliest (if not the earliest) identifiable Medieval Serbian composers and also one of the founders of a new and distinctive style called Serbo-Byzantine school.
