In the past, epic poetry in Kosovo and Northern Albania was sung on a lahuta and then a more tuneful çiftelia was used which has two strings-one for the melody and one for drone. Kosovan music is influenced by Turkish music due to the almost 500-year span of Ottoman rule in Kosovo though Kosovan folklore has preserved its originality and exemplary. Archaeological research tells how old this tradition is and how it was developed in parallel with other traditional music in the Balkans. Roots dating to the 5th century BC have been found in paintings on stones of singers with instruments. (There is a famous portrait of "Pani" holding an instrument similar to a flute).
