What are some similarities between Early New Orleans jazz and Swing?

Early New Orleans jazz and Swing both emphasize improvisation, allowing musicians to express their creativity within a structured framework. Both styles feature a strong rhythm section, often driven by the bass and drums, which propels the music forward. Additionally, both genres incorporate a blend of brass and woodwind instruments, creating rich, vibrant melodies. While Early New Orleans jazz often has a more collective improvisational feel, Swing focuses on arranged sections and a smoother, more danceable rhythm.
