The horn is a brass instrument made of tubing wrapped into a coil with a flared bell. The double horn in F/B♭ is the horn most used by professional bands and orchestras.
The proper name of the horn is simply the horn, or horn in F. "French Horn" is a colloquial term for the instrument that is not officially recognized in the professional music world.
Pitch is controlled through the adjustment of lip tension in the mouthpiece and the operation of valves by the left hand, which route the air into extra tubing.
The main tubing on an F horn is about 12–13 ft (3.7–4.0 m) long and that associated with the valves adds additional length to achieve up to about 17 ft (5.2 m) of tubing overall.
A musician who plays any kind of horn is called a horn player (or less frequently, a hornist).
As portrayed in Hibike! Euphonium
There are five students that play horn in Kitauji's Concert Band including:
- Jyuri Sawada - Principal Horn
- Miru Kishibe
- Hiro Kahashi
- Lala Hitomi
- Michiyo Morimoto
- Horn instrumentation is written as "F Horn" in band music. Many people take this as an abbreviation of "French Horn," when in reality, the F mean "key of F," since the horn is pitched in F as opposed to C.
- The standard name for this instrument is horn. "French Horn" is a colloquialism.
- Horn players hate playing marches by John Phillip Sousa, which is basically every popular American patriotic march. Horn players hate them. Want to know why?
- Horn players have two stereotypes. One applies more to school bands; it is said that student horn players are unmotivated, lazy, and are late in transitioning through puberty because of their constant cracking of notes. The other stereotype applies to the horn players who actually made it through life and managed to major in horn and become professionals. These people are as cold as ice, tough as steel, and fiery as the sun. They are not to be messed with.
- In Hibike! Euphonium, the horn section notably seems to change significantly from the former stereotype to the latter over the course of the first season; they tend to be used as a showcase of how the band is becoming more determined and serious. As a result they are arguably among the most well-developed secondary characters.
