According to Aristotle, a tragedy must always respect three aspects, or, three unities. The unity of time, the unity of place, and the unity of action. This means that a tragedy must always be watched in one sitting, up to a maximum of 24 hours of length; it must be held in its entirety at a single place; and one should not have multiple parallel plots and should focus on just one action.
According to Aristotle, a tragedy must center on the suffering of a tragic hero or heroine.
In his work on Poetics, Aristotle defines tragedy in this way: "Tragedy is a form of drama exciting the emotions of pity and fear. Its action should be single and complete, presenting a reversal of fortune, involving persons renowned and of superior attainments, and it should be written in poetry embellished with every kind of artistic expression."
In his thoughts on Poetics (or what we would call the dramatic arts), Aristotle also asserted that every tragedy (a dramatic, serious play) contains six elements: "Plot, Character, Diction, Thought, Spectacle, Song."
