What compositional technique is often utilized in big bands?

The compositional technique often utilized in big bands is arranged music with written parts. In big band jazz, arrangements are essential for organizing the performance of a large ensemble, which typically includes sections for brass, woodwinds, and rhythm instruments. This structured approach allows for complex harmonies, melodies, and orchestrations that highlight the unique timbres of different instruments within the band. Arrangements often feature written scores that dictate the roles of each musician, the dynamics, and the overall form of the piece, ensuring that everyone plays in synchrony during performances. This emphasis on arranged music contributes to the cohesive sound and intricate arrangements characteristic of big band jazz.
