Question

Quizplus · Accepted Answer

On brass instruments, sound is produced when the player's lips vibrate as air is blown between them into the small cup-shaped mouthpiece. The vibration of the lips sets the column of air inside the instrument in motion, which produces a sound wave that travels through the instrument and out of the bell.
