Gypsy jazz is a genre developed in France that combines Jazz with several aspects of Romani Folk Music. Although many instrument lineups are possible, the guitar and violin are the most common solo instrument, standing starkly in contrast to typical jazz, where saxophones, trumpets, etc. are far more common. Clarinet and accordion are also commonly used, and the rhythm guitar is often played with a percussive technique known as "la pompe", largely replacing the drums. Django Reinhardt was a major figure in creating the genre by helping to fuse the aforementioned gypsy elements with the Swing sound of his era.
