text: Modern French horns have three valves which lower the pitch a semitone, a tone, and three semitones (minor third).
text: Some modern flugelhorns feature a fourth valve that lowers the pitch a perfect fourth (similar to the fourth valve on some euphoniums, tubas, and piccolo trumpets, or the trigger on trombones).
text: Since valves lower the pitch, a valve that makes a pitch too low (flat) creates an interval wider than desired, while a valve that plays sharp creates an interval narrower than desired.
text: In instruments with a fourth valve, such as tubas, euphoniums, piccolo trumpets, etc. that valve lowers the pitch by a perfect fourth; this is used to compensate for the sharpness of the valve combinations 1–3 and 1–2–3 (4 replaces 1–3, 2–4 replaces 1–2–3).
text: Each valve lowers the pitch by adding extra length: the first valve by 2 semitones the second valve by 1 semitone and the third valve by 3 semitones
