The French horn (since the 1930s known simply as the "horn" in some professional music circles) is a brass instrument made of tubing wrapped into a coil with a flared bell. The double horn in F/B (technically a variety of German horn) is the horn most often used by players in professional orchestras and bands. A musician who plays a French horn is known as a horn player or hornist.

Pitch is controlled through the combination of the following factors: speed of air through the instrument (controlled by the player's lungs and thoracic diaphragm); diameter and tension of lip aperture (by the player's lip muscles—the embouchure) in the mouthpiece; plus, in a modern French horn, the operation of valves by the left hand, which route the air into extra sections of tubing.[2] Most horns have lever-operated rotary valves, but some, especially older horns, use piston valves (similar to a trumpet's) and the Vienna horn uses double-piston valves, or pumpenvalves. The backward-facing orientation of the bell relates to the perceived desirability to create a subdued sound in concert situations, in contrast to the more piercing quality of the trumpet. A horn without valves is known as a natural horn, changing pitch along the natural harmonics of the instrument (similar to a bugle). Pitch may also be controlled by the position of the hand in the bell, in effect reducing the bell's diameter. The pitch of any note can easily be raised or lowered by adjusting the hand position in the bell.[3]

Three valves control the flow of air in the single horn, which is tuned to F or less commonly B. The more common double horn has a fourth, trigger valve, usually operated by the thumb, which routes the air to one set of tubing tuned to F or another tuned to B which expands the horn range to over four octaves and blends with flutes or clarinets in a woodwind ensemble. Triple horns with five valves are also made, usually tuned in F, B, and a descant E or F. There are also double horns with five valves tuned in B, descant E or F, and a stopping valve, which greatly simplifies the complicated and difficult hand-stopping technique[4], though these are rarer. Also common are descant doubles, which typically provide B and alto F branches.

French horns are notoriously difficult to play at very low tones (called "pedal tones") or high notes which have close harmonics and often flubbed by sliding from a nearby pitch, or even trilling to regain the higher notes. Although many instruments have technical issues, the horns tend to be louder in solo parts so that mistuned notes or flubbing is easy to hear, and audio engineers often remove or smooth the recording for flubbed horn notes of top professional orchestras.

A crucial element in playing the horn deals with the mouthpiece. Most of the time, the mouthpiece is placed in the exact center of the lips, but, because of differences in the formation of the lips and teeth of different players, some tend to play with the mouthpiece slightly off center.[5] Although the exact side-to-side placement of the mouthpiece varies for most horn players, the up-and-down placement of the mouthpiece is generally two-thirds on the upper lip and one-third on the lower lip.[5] When playing higher notes, the majority of players exert a small degree of additional pressure on the lips using the mouthpiece. However, this is undesirable from the perspective of both endurance and tone: excessive mouthpiece pressure makes the horn sound forced and harsh, and decreases player's stamina due to the resulting constricted flow of blood to the lips and lip muscles.[6]


The name "French horn" is found only in English, first coming into use in the late 17th century. At that time, French makers were preeminent in the manufacture of hunting horns, and were credited with creating the now-familiar, circular "hoop" shape of the instrument. As a result, these instruments were often called, even in English, by their French names: trompe de chasse or cor de chasse (the clear modern distinction between trompes, trumpets, and cors, horns, did not exist at that time). German makers first devised crooks to make such horns playable in different keys—so musicians came to use "French" and "German" to distinguish the simple hunting horn from the newer horn with crooks, which in England was also called by the Italian name corno cromatico (chromatic horn).[7] More recently, "French horn" is often used colloquially, though the adjective has normally been avoided when referring to the European orchestral horn, ever since the German horn began replacing the French-style instrument in British orchestras around 1930.[8] The International Horn Society has recommended since 1971 that the instrument be simply called the horn.[9][10]

There is also a more specific use of "French horn" to describe a particular horn type, differentiated from the German horn and Vienna horn. In this sense, "French horn" refers to a narrow-bore instrument (10.8–11.0 mm [0.43–0.43 in]) with three Périnet (piston) valves. It retains the narrow bell-throat and mouthpipe crooks of the orchestral hand horn of the late 18th century, and most often has an "ascending" third valve. This is a whole-tone valve arranged so that with the valve in the "up" position the valve loop is engaged, but when the valve is pressed the loop is cut out, raising the pitch by a whole tone.[11]
