My Sweet is an instrumental gypsy jazz tune by Django Reinhardt and Stéphane Grappelli, both credited as its composers. The original recording was made by the Quintette du Hot Club de France, with Reinhardt and Grappelli, for His Master's Voice in Paris. The session is dated 22 April 1937, although that year is not confirmed on the compilation master. The Quintette defined the gypsy jazz style of the 1930s, and the tune shows it in the exchanges between guitar and violin.
The recorded version runs about 2:55 and is in the key of C. The piece has no lyrics, so the melody and the dialogue between the two soloists carry the whole performance. It has been reissued on compilations of the Quintette's 1930s recordings, which keeps the original version available to musicians and listeners.
