Schubert's "Ave Maria (Ellen's Song No. 3)": Poetic Structure Analysis Using the C4 Model

This research conducts a multi-layered analysis of the poetic structure of Franz Schubert's "Ave Maria (Ellen's Song No. 3)" D.839 by individually decomposing each layer of the C4 Model (Context, Container, Component, Code). In contrast to the integrative approaches in traditional literary studies, this study aims to objectively elucidate the structural perfection of the work by individually examining the functions and interrelationships of each layer. The C4 Model, originally developed for software architecture visualization, provides a systematic framework for analyzing complex hierarchical structures. The analysis reveals a dual-axis structure in the Context layer, three-stage progression in the Container layer, emotional transition system in the Component layer, and strategic placement of linguistic techniques in the Code layer. Each layer maintains independence while producing an integrated poetic effect. The methodology employs PlantUML C4 notation for visualization and documentation, enabling precise structural mapping of poetic elements. This interdisciplinary approach demonstrates how computational methods can enhance literary analysis, offering new perspectives on classical works. The findings contribute to digital humanities scholarship by establishing a replicable framework for systematic poetic structure analysis that bridges software engineering principles with literary criticism.
