Although both baritone horn and euphonium produce partials of the B♭ harmonic series in the same range, and both have a nine-foot-long main tube, the baritone horn tends to have a smaller and more cylindrical bore than the euphonium. The baritone horn usually has a tighter wrap and a smaller bell, and is thus smaller and lighter overall, and produces a "lighter" sound versus the more solid, brassy timbre of the euphonium
