Aristotle analyzed tragedy in his work "Poetics". He defined tragedy as an imitation of events that are serious, complete with magnitude, and use embellished language to elicit pity and fear, resulting in catharsis. The key elements of tragedy include plot, character, thought, spectacle, melody, and language. A good plot should have magnitude, unity, and a beginning, middle and end. It involves reversal and recognition, and the hero should fall due to a hamartia, or tragic flaw. Tragedy should represent terrible yet piteous events and have a realistic ending without deus ex machina. The chorus should be part of the whole work.
