According to Aristotle in what ways Tragedy is superior to epic?

Tragedy vs. Epic Poetry

In Aristotle's time, the critics considered epic poetry to be the supreme art form, but to Aristotle, tragedy is the better of the two forms. Aristotle believes that tragedy, like the epic, can entertain and edify in its written form, but also has the added dimension of being able to translate onstage into a drama of spectacle and music, capable of being digested in one sitting.
