This document discusses Aristotle's six parts of tragedy according to his work Poetics. The six parts are plot, character, thought, diction, song or melody, and spectacles. Plot is considered the most important part as it is the soul of tragedy and refers to the harmonious arrangement of all incidents. Character focuses on the hero in tragedies. Thought proves particular points and teaches truth. Diction is the expression of meaning in words. Song or melody refers to the role of the chorus. Spectacles involve stage performance but should not create a sense of the monstrous.
