This document summarizes several brass instruments: the baritone, which is half the size of a tuba and plays in the trombone range; the trumpet, which has the brightest tone and 3 valves; the cornet, which is similar to the trumpet but has a wider bore; the horn, which has a mellow, majestic tone; the trombone, which uses a slide instead of valves; and the tuba, which plays the lowest notes and strengthens the bass line.
