A jazz combo typically consists of five instruments: saxes, trumpet, piano, bass, and drums. Saxes are a type of woodwind instrument that produce a smooth, mellow sound. They are often used in jazz music to provide a melodic accompaniment to the other instruments. Trumpet is a brass instrument that produces a bright, powerful sound. Piano is a keyboard instrument that can be used to create a wide range of sounds. Bass is a stringed instrument that provides a low-pitched foundation for the other instruments. Drums are percussion instruments that provide a rhythmic beat. Together, these five instruments form the core of a jazz combo.
