A traditional jazz band typically consists of the following instruments:
1. Trumpet: there can be one or two players
2. Trombone: usually two players.
3. Clarinet: usually one player.
4. Saxophone: Usually one of each type (alto, tenor, and baritone).
5. Piano: plays chords, melody, accompanies, and often performs improvisations.
6. Double Bass: typically there is only one player playing the bass lines and harmonies.
7. Drums: Usually a drum set played to provide rhythm.
This configuration of instruments is often referred to as a dixieland jazz band. However, there are many other variations of jazz bands, each with its own unique instrumentation. For example, some jazz bands may include a violin, cello, flute, or even a vocalist.
