A comedy, in contrast to a tragedy, is a genre of drama in literature that is characterized by its happy and vivacious ending. Besides making the audience happy, a comedy rather importantly intends to evoke humour and amusement in the audience by means of extensive laughter.
A tragedy is a genre of drama in literature that is mainly characterized by its sad and depressing ending. The play deals with a series of sorrowful events happen to or are caused by its hero or heroine.
