A jazz band is a musical ensemble that plays jazz music. Jazz bands usually consist of a rhythm section and a horn section.

The rhythm section of a jazz band consists of the drums, bass, and usually at least one instrument capable of playing chords, such as a piano or guitar. The rhythm section is the foundation for the band; it sets the feel for the piece.

The horn section consists of wind and brass instruments, which play the melody and main accompaniment. Typical horns found in a big jazz band include 4-5 trumpets, saxophones (2 altos, 2 tenors, and a baritone), and 3-4 trombones and a bass trombone. The saxophones may also double on flute and clarinet and the trumpets on flugelhorn.
