Can you tell me what the difference between a symphony and an opera is?

A symphony is typically composed of four movements, while an opera is usually made up of three. The first movement in a symphony is typically called the introduction, while the last one is often referred to as the coda. In an opera, the second movement is known as the aria, which is sung by the main character. Additionally, the third movement in a symphony is usually called the development section, while the third movement in an opera is called the recitative.
