The Orchestra

An orchestra is an ensemble of musicians who play musical compositions that are designed to be performed by a large group of instruments. In order to be considered an orchestra, the ensemble must have several sections, including  string instruments, woodwinds, and brass instruments, with most also having a percussion section. It is led by a conductor in performance and can perform a wide variety of musical   pieces at all sorts of events. The word is derived from the Greek word for the area of the stage where the chorus sang and danced during performances in Ancient Greece.
