The first group of symphony orchestra instruments, the most extensive and probably the most recognizable are stringed bowed instruments.This includes violin, viola and cello, which is usually during the concert are on the "front line", directly in front of the conductor, and double basses.All of these tools are a wooden deck with a strained over the strings, which is played with a bow.Form deck at all representatives of this music "family" of the same varies its size and, accordingly, the height of the sound emitted.The violin has the highest order and at the same time is the most important instrument in a symphony orchestra.Just below the sounding viola, then the cello.The lowest sound has bass, which usually acts as a rhythm section, in contrast to
the solo violin.
For woodwinds include tools, the principle of sound which is based on the vibration of air in the hollow tube, where with the help of valves varies the pitch.Despite the name, date of this group can not be made of wood, and of metal, plastics or glass.For example, the orchestral flute is usually made of the alloy, which may include and precious metals.Company they constitute oboe, clarinet and the lowest sounding woodwind instrument - bassoon.Externally, as a rule, they are long tubes with valves, holes from the top, the air in which the musician is served directly from their lungs.This group also includes saxophone, but it is not a traditional instrument orchestra.
Brass according to the principle of sound similar to their "wooden" brethren, though they differ from them in appearance.In addition, all the tools in this group have a loud sound and bright, due to what are rather limited application in the symphony orchestra, and it is not always fully represented.The most common traditional structure includes trumpet, trombone, French horn, tuba.
rhythm section of a symphony orchestra is a group of percussion instruments.It includes and xylophones, and triangles, and other noisy tools, but most of the orchestra can meet two representatives of the "family".Timpani are large metal drums covered with a membrane on which the artist strikes a special sticks.Also used plates - metal discs that musician holding and hitting against each other.In fact, during the concert, both of these tools may sound only once, but it would certainly be a very busy part of the culmination of the work.
sometimes as part of a symphony orchestra may appear, and other tools.Depending on the creative idea of ​​the author or arranger, the traditional set can be added at a concert harp, an expanded brass or percussion, keyboards (piano, harpsichord) and organ.Modern variations of symphonic music can be heard very specific tools of the genre, from the Irish bagpipes to electric, but directly to the orchestra, they usually are not included.
