The trumpet is a brass aerophone known for its bright, penetrating tone. Sound is produced when the player buzzes their lips into a cup‑shaped mouthpiece, causing a standing wave to form inside the tubing. The tubing is bent into a rounded shape, and three valves allow the player to change the effective length of the tube, altering the pitch. The modern B♭ trumpet is the most common type. Historically, trumpets served as signaling devices before evolving into musical instruments used in classical, jazz and popular music.
