French Horn History

As the name indicates, humans originally used to blow on the actual horns of animals before starting to emulate them in metal. This original usage survives in the shofar, a ram's horn, which plays an important role in Jewish religious rituals.

Early metal horns were less complex than modern horns, consisting of brass tubes with a slightly flared opening (the bell) wound around a few times. These early "hunting" horns were originally played on a hunt, often while mounted, and the sound they produced was called a recheat. Change of pitch was effected entirely by the lips (the horn not being equipped with valves until the 19th century). Without valves, only the notes within the harmonic series are available. The horn was used, among other reasons, to call hounds on a hunt and created a sound most like a human voice, but carried much farther.

In orchestral settings, the horn (or, more often, pairs of horns) often invoked the idea of the hunt, or, beginning in the later baroque, determined the character of the key being played or represented nobility, royalty, or divinity.

Early horns were commonly pitched in B♭ alto, A, A♭, G, F, E, E♭, D, C, and B♭ basso. Since the only notes available were those on the harmonic series of one of those pitches, they had no ability to play in different keys. The remedy for this limitation was the use of crooks, i.e., sections of tubing of differing length that, when inserted, altered the length of the instrument, and thus its pitch.

Orchestral horns are traditionally grouped into "high" horn and "low" horn pairs. Players specialize to negotiate the unusually wide range required of the instrument. Formerly, in certain situations, composers called for two pairs of horns in two different keys. For example, a composer might call for two horns in C and two in E♭ for a piece in c minor, in order to gain harmonics of the relative major unavailable on the C horns. Eventually, two pairs of horns became the standard, and from this tradition of two independent pairs, each with its own "high" and "low" horn, came the modern convention of writing the 1st and 3rd parts above 2nd and 4th.

In the mid-18th century, horn players began to insert the right hand into the bell to change the length of the instrument, adjusting the tuning up to the distance between two adjacent harmonics depending on how much of the opening was covered. This technique, known as hand-stopping, is generally credited to Anton Joseph Hampel around 1750, and was refined and carried to much of Europe by the influential Giovanni Punto. This offered more possibilities for playing notes not on the harmonic series. By the early classical period, the horn had become an instrument capable of much melodic playing. A notable example of this are the four Mozart Horn Concerti and Concert Rondo (K. 412, 417, 477, 495, 371), wherein melodic chromatic tones are used, owing to the growing prevalence of hand-stopping and other newly emerging techniques.

Around 1815 the use of pistons (later rotary valves) was introduced, initially to overcome problems associated with changing crooks during a performance. Valves' unreliability, musical taste, and players' distrust, among other reasons, slowed their adoption into mainstream. Many traditional conservatories and players refused to use them at first, claiming that the valveless horn, or natural horn, was a better instrument. Some musicians, specializing in period instruments, still use a natural horn when playing in original performance styles, seeking to recapture the sound and tenor in which an older piece was written.

The use of valves, however, opened up a great deal more flexibility in playing in different keys; in effect, the horn became an entirely different instrument, fully chromatic for the first time. Valves were originally used primarily as a means to play in different keys without crooks, not for harmonic playing. That is reflected in compositions for horns, which only began to include chromatic passages in the late 19th century. When valves were invented, generally, the French made smaller horns with piston valves and the Germans made larger horns with rotary valves. For more information on instrument valves see brass instrument valve. It is the German horn that is erroneously referred to in the English language (and more commonly in the United States and Canada) as the French horn. There is not a clear consensus on the reason or reasons for this nomenclature, and, as there are conflicting proposals, more research is still necessary.
