Aaron Copland writes, “The tone of the trombone is allied in quality to that of the French horn. It also possesses a noble and majestic sound, one that is even larger and rounder than the horn’s tone. But it also partly belongs with the trumpet, because of its brilliance of timbre in fortissimo. Moments of grandeur and solemnity are often due to a judicious use of the trombone section of the orchestra” (Copland 75-76).
