The Valve Trombone differs from the slide trombone in that you change its pitch by using three valves, as on the orchestral trumpet. These valves give you greater flexibility, but the sound is less brilliant. Until the mid-20th century, valve trombones were common in bands and theater orchestras ; now they are most often heard in jazz.
