This document summarizes several theorists' concepts related to narrative structure and analysis: - Roland Barthes identified 5 codes that provide meaning in narratives: the semantic, hermeneutic, cultural, symbolic, and proairetic codes. - Tzvetan Todorov believed there are 5 stages to narrative structure: equilibrium, disruption, recognition of disorder, attempt to repair damage, and return to a new equilibrium. - Vladimir Propp analyzed Russian folktales and identified 8 common character types and 31 potential "narrative functions" that move the plot forward. - Claude Levi-Strauss viewed the individual narrative as an imaginary resolution to real-life contradictions.
