The documented musical history of the Serbs can be traced back to the medieval era. Church music was performed throughout Serbia by choirs or individual singers. The songs performed at the time were derived from the Osmoglasnik, a collection of religious songs dedicated to Jesus. These songs were repeated over the course of eight weeks in a cyclical fashion. Composers from this era include Stefan Srbin, Isaija Srbin, and Nikola Srbin. Aside from church music, the medieval era in Serbia included traditional music, about which little is known, and court music. During the rule of the House of Nemanjić musicians played an important role in the royal court, and were known as sviralnici, glumci and praskavnici. The rulers known for the musical patronage included Stefan Dušan and Đurađ Branković. With the fall of Serbia under the Ottoman rule came instruments that would further cause Serbian music to flourish. Medieval musical instruments included horns, trumpets, lutes, psalteries, drums and cymbals. Traditional folk instruments include the gajde, kaval, dajre, diple, tamburitza, gusle, tapan (davul), sargija, ćemane (kemenche), zurla (zurna), and frula among others. <a href="https://www.last.fm/music/Serbian+Medieval+Music">Read more on Last.fm</a>.
