A symphony is a lengthy and complex musical composition typically written for a full orchestra. It usually includes multiple movements, each with its own distinct themes and character. Symphonies often explore a range of emotions and can be grand and dramatic, showcasing the capabilities of the orchestra and the creativity of the composer.
The word "symphony" derives from the Greek word "symphonia," which means "agreement" or "concord." It is a combination of "syn-" (together) and "phone" (sound), reflecting the idea of harmonious sounds coming together.
