Structural Analysis of Music of J.S. Bach Using Chemical Principles
許舒堯 芝加哥大學化學博士、隆基音樂學院演奏碩士
Structural analysis of J.S. Bach*s works has always been challenging in traditional tonal theory, which views formal structure as a macroscopic property. We propose two new approaches to describe the structure of Bach*s musical system from the molecular level.
The first approach encompasses treating the time evolution of music as a dynamic process, deriving the “reaction mechanism” that describes the evolution of the system. For example, a recurring pattern can be described as a molecule that undergoes reactions such as isomerization; a tune that started from unison, and then doubled in larger and larger intervals can be described as splitting of degenerate orbitals.
The second approach maps the time evolution of music to spatial domain, which then allows us to examine the symmetry of its structure. For example, a fugue with six entrances of its subject has hexagonal geometry, each entrance a monomer that is slightly altered. A large dance suite can be understood as a protein multimer, each dance movement a different subunit with its own tertiary and secondary structures. Using this approach, we can thus understand the structure of Bach*s works from the microscopic and mesoscopic level, linking it to the macroscopic structure that can be more intuitively understood.
