Jazz violin is the use of the violin or electric violin to improvise solo lines. Early jazz violinists included: Eddie South, who played violin with Jimmy Wade's Dixielanders in Chicago; Stuff Smith; and Claude "Fiddler" Williams. Joe Venuti was popular for his work with guitarist Eddie Lang during the 1920s. Improvising violinists include Stéphane Grappelli and Jean-Luc Ponty. In jazz fusion, violinists may use an electric violin plugged into an instrument amplifier with electronic effects.
