String Instrument

A string instrument (or stringed instrument) is a musical instrument that produces sound by means of vibrating string. In the Hornbostel-Sachs scheme of musical instrument classification, used in organology, they are called chordophones. The most common string instruments in the string family are guitar, violin, viola, cello, double bass, banjo, mandolin, ukulele, and harp. Not often immediately recognized as such, a piano is also a string instrument.

Violin

The violin is a bowed string instrument with four strings usually tuned in perfect fifths. It is the smallest and highest-pitched member of the violin family of string instruments, which also includes the viola and cello.
The violin is sometimes informally called a fiddle, regardless of the type of music played on it. The word violin comes from the Middle Latin word vitula, meaning stringed instrument

An orchestra is an instrumental ensemble, usually fairly large with string, brass, woodwind sections, and almost always a percussion section as well.

The termorchestra derives from the name for the area in front of an ancient Greek stage reserved for the Greek chorus. The orchestra grew by accretion throughout the eighteenth and nineteenth centuries, but changed very little in composition during the course of the twentieth century.

A smaller-sized orchestra for thistime period (of about fifty players or fewer) is called a chamber orchestra. A full-size orchestra (about 100 players) may sometimes be called a "symphony orchestra" or "philharmonic orchestra"; these prefixes do not necessarily indicate any strict difference in either the instrumental constitution or role of the orchestra, but can be useful to distinguish different ensembles based in the same city (for instance, the London Symphony Orchestra and the London Philharmonic Orchestra).

A symphony orchestra will usually have over eighty musicians on its roster, in

some cases over a hundred, but the actual number of musicians employed in a particular performance may vary according to the work being played and the size of the venue. A leading chamber orchestra might employ as many as fifty musicians; some are much smaller than that.
