Balkan jazz is an umbrella term for jazz from different parts of the Balkan peninsula in southeastern Europe.[1][2] Jazz in the region may incorporate various types of Balkan music, especially folk musics (including "gypsy style"[3]). It has embraced improvisation and originality, much like jazz traditions in the Americas and elsewhere. Characteristic features can include use of unusual meters ("odd rhythms"),[1] sometimes played very fast. There are many venues for Balkan jazz, which is also frequently played at weddings and big celebrations. The clarinet is often a key instrument in keeping with folk music traditions, and the accordion, drum, bass and electric guitar are also widely used.
