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
