A computer language proving Bach is “Art” mathematically.
To compute the complexity of Bach’s line in the tonal system, a mathematical model of the computational language named β was created based on the theory of quantum logic by Garrett Birkhoff and John von Neumann. As the quantum physics show the elementary particle take non-binary state and it contradicts with our ordinary logic, this language exploits this special logic and computes enormous combinations to achieve the true deductive inference on quantum mechanics.

On the Computational Evolutionary Interpretation of the Golden Ratio and the Class of Functions Created by the Almost Periodic Structure
Descartes, Newton, and da Vinci believed that "ratios" govern all things and tried to unravel the structure of ratios in astronomy, music, and light. In the theory of computational evolution, the Golden Ratio is considered to be built into nature in such a way that it is intuitively recognizable and proves that life is a more complex entity that evolved over time by generating an almost cyclic structure in the evolving = computation = transformation that transitions from one time to the next.
