1. Tragedy: This is the most famous and influential form. It typically deals with serious themes like fate, free will, moral dilemmas, and the consequences of human actions. The characters often face great suffering and loss, and the endings are usually tragic, but with a sense of catharsis (emotional release) for the audience.
2. Comedy: This form is lighter and more humorous than tragedy. It often satirizes social conventions and political figures, and features farcical situations, slapstick, and witty dialogue. The characters are often stereotypical and exaggerated, and the endings are usually happy.
3. Satyr Play: This type of play was a short, comic interlude performed between tragedies. It featured a chorus of satyrs (half-human, half-goat creatures) who were known for their ribald humor and sexual suggestiveness. Satyr plays often parodied the themes and characters of the tragedies.
These three types represent the foundation of Western theatre, and their influence can still be seen in modern plays, movies, and even television shows.
