Narrative is defined as a chain of causal events organized in time with a beginning, middle, and end. Theories of narrative propose that stories follow common patterns, such as having limited character types like heroes, villains, and helpers, and codes like action, references, and symbols. Narrative also involves resolving conflicts, such as between good and evil, innocence and deception, or domestic safety versus wild danger, as seen in resolving the conflict between a geek girl and her crush in Taylor Swift's music video through disequilibrium and resolution.
