Klezmer is a Jewish folk musician of eastern Europe, played by small, traditionally itinerant bands. Musicologists have noted similarities between Klezmer and other improvisational styles such as gypsy music and jazz. Klezmer is a Yiddish name that can either be applied to the type of music – or the musician playing the music. The term derives from two Jewish words: kle (vessel or instrument) and zemer (song), literally meaning “instrument or vessel of song”. Klezmer was first used to describe the traditional instrumental music of Yiddish speaking Jews in Eastern Europe.
