bell
The flared opening at the end of a brass or woodwind instrument that projects the sound outward.
In Depth
French horn players can change the pitch by up to a semitone just by moving their hand deeper into or out of the bell — making it one of the few instruments where the performer physically shapes the sound after it leaves the mouthpiece.
