Gypsy jazz (also known as gypsy swing or hot club jazz) is a style of jazz music often said to have been started by guitarist Jean "Django" Reinhardt in the 1930s. Because its origins are in France it is often called by the French name, "jazz manouche", or alternatively, "manouche jazz", even in English language sources. The term is now commonly used for this style of music.
Django was foremost among a group of Romani guitarists working in and around Paris in the 1930s through the 1950s, a group which also included the brothers Baro, Sarane, and Matelo Ferret and Reinhardt's brother Joseph "Nin-Nin" Reinhardt.
Many of the musicians in this style worked in Paris in various popular Musette ensembles. The Musette style waltz remains an important component in the gypsy jazz repertoire. Reinhardt was noted for combining a dark, chromatic gypsy flavor with the swing articulation of the period. This combination is critical to this style of jazz. In addition to this, his approach continues to form the basis for contemporary gypsy jazz guitar. Reinhardt's most famous group, the Quintette du Hot Club de France, also brought fame to jazz violinist Stéphane Grappelli.
The original Quintette du Hot Club de France played acoustically without a drummer, facilitating the use of the acoustic guitar as a lead instrument. Guitar and violin are still the main solo instruments, although clarinet, mandolin, and accordion are also common. The rhythm guitar is played using a distinct percussive technique, "la pompe", which essentially replaces the drums. Most gypsy jazz guitarists, lead and rhythm, play a version of the Selmer-Maccaferri guitar design favored by Reinhardt himself.
