The terms "symphony" and "orchestra" are often used interchangeably, but they have distinct meanings. Here are the differences between the two:

  • Symphony: A symphony is a large-scale musical composition, usually with three or four movements, that requires 50-80 instruments to perform. It is a type of music, not a group of musicians. The term "symphony" comes from the Greek word "symphōnía," which means "agreement of sound".
  • Orchestra: An orchestra is a large musical ensemble typically containing string, woodwind, brass, and percussion instruments. It is a group of musicians, not a specific type of music. The term "orchestra" comes from the Greek word meaning "a place where contests take place".

A symphony orchestra (often just called "a symphony" for short) is an orchestra that has both the symphony and the orchestra aspects. It is the largest type of orchestra and is composed of strings, brass, woodwinds, and percussion. Symphony orchestras are also sometimes referred to as philharmonic orchestras, with "philharmonic" meaning "loving music" and often used to differentiate between two orchestras in the same city, such as the Vienna Symphony Orchestra and the Vienna Philharmonic Orchestra.

In summary, a symphony is a large-scale musical composition, while an orchestra is a group of musicians with various instruments. A symphony orchestra is a large orchestra that performs symphonies and other types of music.
