Name a prominent Black jazz musician who helped shape the genre in the 20th century, besides Louis Armstrong.

• A. Charlie Parker
• B. Louis Armstrong
• C. Miles Davis
• D. Duke Ellington

Answer: (D)

Jazz in the 20th century grew strongest when musicians treated it as composition and arrangement as much as improvisation. Duke Ellington embodies that shift as a premier composer and big-band leader whose work showed how a jazz orchestra could be a sophisticated, color-rich instrument in its own right. Over decades, he built a large ensemble that could explore intricate harmonies, varied textures, and long-form pieces, turning the orchestra into a storytelling tool rather than just a backdrop for solos. His pieces—standards that became part of the jazz repertoire—demonstrated how mood, color, and thematic unity could carry a whole performance, elevating jazz to a high-art form. Leading bands from the Harlem Renaissance era through the swing era and beyond, Ellington helped popularize and legitimize this expansive vision of jazz, influencing countless musicians and shaping the genre’s direction for generations. While other pioneers pushed jazz in new directions, Ellington’s enduring contribution as a master composer and orchestrator makes him the standout figure described here.
