orchestra

In popular use, orchestra, symphony, and philharmonic are often used interchangeably to refer to a large group of musicians assembled to play music, especially classical music.

The most common (and general) term is orchestra. Most large orchestras include many different instruments and classes of instruments, including strings, woodwinds, brass, and percussion.

The word symphony primarily refers to a complex, multipart musical composition (like Beethoven’s fifth symphony), but it’s also a short way of referring to a symphony orchestra—a large orchestra, the kind that performs symphonies. (Smaller orchestras—those with about 25 people—are often called chamber orchestras). As a noun, the word philharmonic can refer to a symphony orchestra or to the organization that sponsors it (sometimes called a philharmonic society, in which philharmonic is used as an adjective). The word orchestra most commonly refers to the group of musicians, but it can also refer to the space reserved for them, usually the front part of the main floor (sometimes called the orchestra pit).

Both symphony and philharmonic are sometimes used in the names of orchestras, as in the Chicago Symphony Orchestra, the New York Philharmonic, and the London Philharmonic Orchestra.
