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.
Gypsy jazz, along with traditional Gypsy music, is learned by the passing down of knowledge from older generations. Many Gypsy musicians do not read notated music. It is more common for beginners to spend hours learning and memorizing songs from recordings and gleaning techniques from more experienced players.
