Aristotle identified six constituent parts of tragedy: plot, character, thought, diction, song, and spectacle. The plot is the most important part and includes a logical sequence of events with a beginning, middle, and end. Character supports the plot and consists of good, appropriate, true to life, and consistent characters. Thought proves ideas and includes themes. Diction is the selection of words used. Song is found in choral parts and adds narrative style. Spectacle involves scenic effects but should not be relied upon by the dramatist.
