Orchestra

n. band composed of musicians of many different instruments (usually including string and wind instruments); space reserved in front of a stage for musicians (Theatre)

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