"Minor Blues," also known as "Blues en Mineur," is a jazz composition co-written by Django Reinhardt and Stéphane Grappelli. The piece was first recorded in 1942, becoming one of the early standards of jazz manouche. It draws inspiration from their earlier work, "Minor Swing," and showcases the quintet's unique blend of swing and blues influences. The composition has since become a staple in the gypsy jazz repertoire, frequently performed at jams and festivals.
