Can you explain the difference between a symphony and an orchestra?

A symphony is typically a large-scale orchestral composition, usually lasting around 40 minutes or longer. An orchestra is made up of many different instruments that are played together to create music. The main difference between a symphony and an orchestra is that a symphony typically has one conductor who leads the entire ensemble while an orchestra may have multiple conductors for each section of the piece. Additionally, a symphony often features a solo instrument such as a piano, violin, or cello while an orchestra can feature any number of instruments at once.
