Every brass instrument comprises mouthpiece, mouthpipe, main pipe, and flared bell

Evidence

All brass instruments consist of four sections (see Figure 4.26): mouthpiece, a tapered mouthpipe, a main pipe fitted with slide or valves that is cylindrical (e.g., trumpet, French horn, trombone) or conical (e.g., cornet, flugelhorn, baritone horn, tuba) and a flared bell (Benade, 1976; Hall, 2001). — David M.
