In modern orchestras, the French horn, also known as the French horn, is one of the most beautiful and charming instruments, and it is also considered as the most difficult instrument to play. The length of the silver (or copper) tube is 3.7 meters (12 feet), and it is coiled into a circle. Horn is a brass instrument with warm and soft timbre, but it can also play a higher pitch. Because it can blow out two kinds of horn sounds at the same time, it is also called double horn.

Brass instruments can produce shocking sound effects, which are not only used in the battlefield, but also an indispensable favorite in major celebrations. When powerful and solemn timbre is needed, brass instruments are usually the first choice.

French horn occupies a very prominent position in the family of brass instruments, but because its range is not very wide, it used to be only suitable for playing powerful explosive noises. It was not until the 18 15 piston was invented and applied to the French horn that the situation changed.

Using piston can enlarge the range of brass instruments and make the timbre more accurate. Musicians also found that there is a closed-tone playing method, in which the hand is put into the funnel-shaped trumpet, which can increase the range, but the sound quality is poor.

This improvement had a far-reaching impact on the French horn. Its predecessor is the hunting horn used by the French when hunting, just a rounded corner with a horn.

However, after the use of the piston, the range and timbre of the French horn became wider, and it was introduced into opera performance by Belgian composer Gersek in 1827.

In the orchestra, the French horn gradually occupied an important position. It enables composers not only to write insignificant harmony in orchestration, but also to easily combine with woodwind instruments and even stringed instruments to provide warm and full harmony for orchestras.

In orchestral music, the most commonly used "even number" is actually a combination of two numbers. People often refer to this instrument as the French horn, which is actually a saying that many a mickle makes a mickle. Its shape is long and narrow, and its tail expands into a funnel-shaped bell mouth; A * * * has four valves, just like a small one. Three valves are used as chromatic scales, but its valves are rotary. The opening of the fourth valve is in a long tube, which is specially used to blow the bottom sound, which is why this instrument is called double horn. There is a gentle and deep voice from the long pipe, and a high-pitched tune from the short pipe; Therefore, the sound of the bugle is soft and clear, and occasionally a cheerful music is inserted.

The right hand is usually placed at the bell mouth to control the timbre and timbre; If you insert the trumpet with your right hand up, it will produce a slightly harsh sound, so you rarely use mute when playing. French horn is a transposed instrument, and its timbre is F.
