  • n. A wind-instrument more or less resembling a horn in shape and size, and originally made of horn: as, a hunting-horn; a tin horn. In the simpler forms the horn is used chiefly to give signals, producing single or slightly variable loud tones. The hunting-horn, however, was early elaborated and made capable of producing a variety of calls, fanfares, and simple tnnes. Wood, ivory, and various metals have been used for making horns.
  • n. By extension, a musical wind-instrnment of the trumpet class, developed from the hunting-horn (previously modified for use in orchestras under the name corno di caccia), and distinctively called the French horn, having a slender tube of brass or silver, several feet long, gracefully curved upon itself, terminating in a flaring bell, and blown through a mouthpiece of conoidal bore. Its tones are harmonics of the natural tone of the tube, produced by slightly varying the method and pressure of the blowing. Its compass is about four octaves, the series of tones in the two upper octaves being diatonic and partially chromatic. In addition to these primary or open tones, modified or closed tones are produced by inserting the hand into the bell, so as to alter the pitch of an open tone chromatically. The pitch of the fundamental tone, and thus of the whole series of open tones, is altered by detachable crooks, which increase the actual length of the tube. From eight to twelve such crooks are made, pitching the instrument in nearly all the chromatic keys between the second C below middle C and the second Bb below that. The key in which the instrnment is to be set is indicated at the beginning of each piece; but the music is written in the key of C. The pitch of the tube is still further affected by the tuning-slide, which is one of the curves of the tube so arranged that it can be pushed in or out at will. Ventils or valves are sometimes added to the tube to facilitate rapid passages. Horns are the most valuable orchestral instruments of their class. Their tone is mellow, pervasive, and blending, with a peculiar romantic quality. The French horn is sometimes used singly or as a solo instrument, but in orchestras it is nearly always combined in pairs or in quartets, and used both for melodic effects, especially in fanfares and similar figures, and for sustained chords as a harmonic basis for free instrumentation.
