Tenor horn horn is a valved brass instrument (in E) which has a predominantly conical bore like the baritone horn and flugelhorn. It uses a deep funnel- or cup-shaped mouthpiece. The tenor horn's conical bore and deep mouthpiece produce a mellow, rounded tone which is often used as a middle voice, supporting the melodies of the trumpets, cornets or flugelhorns, and filling the gap above the lower tenor and bass instruments (the trombone, baritone horn, euphonium and tuba). Its valves are typically, though not exclusively, piston valves. The tenor horn has been made and is made in various shapes: the most common
Pitch of brass instruments normal playing range of most three-valved brass instruments extends from three whole tones below the 2nd harmonic of the instrument to the 10th harmonic. Skilled players can produce tones outside this range. For many transposing brass instruments, this range is written as extending from F♯ below middle C to E two octaves and a third above middle C. The orchestral horn is an exception as it was classically assigned a range beginning at its fourth harmonic. The ease with which a player produces the fundamental note of each harmonic series for each tubing length of a modern brass instrument varies
