The Evolution of Harmonic Systems and Complex Structural Architectonics in Music Theory

This expanded scientific article explores the intricate layers of music theory, focusing on the transition from modal polyphony to functional harmony. It provides a deep-seated analysis of the hierarchical structure of tonal functions, the expansion of dissonance in classical harmony, and the dialectical development of the sonata-allegro form. The work also examines the relationship between musical syntax and the psychological perception of structural boundaries, providing a comprehensive theoretical framework for understanding Western classical composition.
