Usage

What’s the difference between a symphony, an orchestra, and a philharmonic? In popular use, symphony, orchestra, 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. Here’s an example of symphony, orchestra, and philharmonic used correctly in a sentence. Example: I’ve attended performances of this symphony by the Berlin Philharmonic, the Philadelphia Orchestra, and the Boston Symphony Orchestra. Want to learn more?

Explanation

A symphony is the name of a type of classical music (a long, complex sonata) and the large orchestra that plays that music. If you go to a concert hall to see a piece of Beethoven or another composer, you're going to hear a symphony — a type of complicated, orchestral music played by a symphony orchestra. A symphony usually includes strings, horns, drums, piano and has a conductor to lead the group by waving a baton. You can also use this word as a comparison: A gorgeous spring day could be called a symphony of beauty and new life.
