This setup allows for a rich blend of melodies and harmonies, showcasing the improvisational nature of jazz music. Jazz quartets often perform in various settings, from small clubs to larger concert halls. They play a mix of original compositions and jazz standards, allowing for creative expression and interaction among the musicians. The quartet format is popular for its balance of individual solos and cohesive group performance.
