Interpretive essays are writings in which the writer attempts to interpret the work of another author. To do this, the author's techniques must be identified, evaluated, and analyzed. Also, his or her intentions must be understood. The reader does not simply follow the narrative structure of the essay; instead, he or she thinks about what has been written and draws conclusions about its meaning. Some examples of interpretive essays include analyses of paintings, sculptures, and diagrams; discussions of films, plays, or songs with specific lyrics; and examinations of historical figures or events from different perspectives. Writers often use other sources to inform their interpretations of art works, music albums, movies, etc. For example, one might study famous artists' biographies for information on how they developed as painters, or read contemporary reviews of a film before seeing it himself/herself to understand why it was made and what kind of message it sends about society. In addition to using other sources to help interpret art works, writers also use their own experiences when creating essays that discuss music albums, books, or movies. For example, one might write an essay on how John Lennon changed after he was shot by Mark David Chapman during Lennon's visit to Japan because it illustrates how tragedy can change a person's life forever.
