According to Aristotle TRAGEDY has six formative parts. They are :
1) Plot(muthos),
2) Character(ethos),
3) Thought(dianoia),
4) Diction(lexis),
5) Song(melos), and,
6) Spectacle(opsis).
The most important element of tragedy is plot. Plot is the soul of tragedy. Plot means 'the arrangement of the incidents.' Normally the plot is divided into five acts, and each act is further divided into several scenes. The dramatist's main skill lies in dividing the plot -- acts and scenes-- in such a way that they may produce the maximum scenic effect in a natural development.
Character
Characters are the men and women who act. The hero and heroine are two important figures among the characters. The characteristics of an ideal tragic hero, according to Aristotle are:
a) He must be good,
b) His character must be appropriate to his station in his life,
c) He must possess a likeness to human nature, and,
d) His character must be consistent. He must be consistent even in his inconsistency.
Thought
Thought means what the characters think or feel during their career in the development of the plot. The thought is expressed through their speeches or dialogues.
Diction
Diction is the medium of language or expression through which the characters reveal their thoughts and feelings. The diction should be powerful enough to do the task.
Song and Spectacle
Spectacle and song are part of the stage equipment. Grand make-up and costumes are used by actors. The tragic character usually wore a particular kind of boots to appear taller. Music is related mainly to chorus singing.
