Narrative theory describes approaches to understanding narratives or storytelling. The main theorists discussed are Claude Levi-Strauss, Vladimir Propp, and Tzvetan Todorov. Levi-Strauss focused on binary opposites like day/night structuring texts. Propp identified 32 character categories in folk tales, like hero and villain. Todorov proposed 5 stages to writing a narrative: equilibrium, disruption, realization, attempt to repair, and restoration of equilibrium. The document discusses applying these theories to a music video by using opposites, including defined characters, and employing flashbacks with an unconventional ending.
