Rural folk traditions in Bosnia and Herzegovina include the shouted, polyphonic ganga and "ravne pjesme" (''flat song'') styles, as well as instruments like a droneless bagpipe, wooden flute and šargija. The gusle, an instrument found throughout the Balkans, is also used to accompany ancient Slavic epic poems. There are also Bosnian folk songs in the Ladino language, derived from the area's Jewish population.
