The so-called musical instruments in which the sound occurs due to the oscillation of the air in the hollow tube. Some of them are straight and relatively short, as the clarinet, flute or oboe. Other long, for convenience, "collapsed"as the bassoon, horn, trumpet.
Some are made of wood, others of metal. And shape tools, and the material from which they are made, are of great importance: they determine the nature, colour of sound, i.e. the sound.
A special role is played by the material: the sound of metal is quite different than that of wood. Therefore, wind instruments are divided into two groups - wood and brass. But they all have one thing in common: unlike keyboards and stringed instruments they are monophonic. Each tool can perform only one melody. Therefore, in the orchestra are usually two or more instruments of the same species.
When playing woodwind instruments current of air is sent into the special hole, and to adjust the height of the sound used holes and closing their valves. This group of instruments received its name due to the fact that before they were made only of wood. Some modern instruments of this type, for example, flute, wood almost never do, and for the manufacture of other along with the tree used metal.
The wooden wind instruments include the flute and the block-flute, oboe, clarinet, bassoon, saxophone, and such folk instruments such as the Hornpipe, the pipe and zurna.
Wooden wind instruments
The principle of the game on brass instruments is that the sounds are obtained by blowing into them air flow. The change in pitch is achieved by the position of the lips and regulation of the force of blown air. As in the case of wooden wind instruments, the name of the wind historically happens from the material from which they originally made, but now, in addition to copper, is used in the production of brass, silver.
For brass instruments include tuba, French horn, trumpet, cornet, trombone, Helicon, VII.
