Definition & Meaning of "trombone"

What is a "trombone"?

A trombone is a brass instrument with a long, slide mechanism that changes the pitch. It has a cylindrical tube that curves into a bell shape. The player produces sound by buzzing their lips into a mouthpiece, and the pitch is adjusted by moving the slide to lengthen or shorten the tubing. This slide allows the trombone to play a wide range of notes smoothly and continuously. Known for its powerful, rich tone, the trombone is used in various musical genres, including classical, jazz, and marching band music.
