Harmonic Interference Theory is a set of thirty-four principles that explain music perception using the underlying physics of a harmonic standing wave. Based on a mathematical balance between maximum resonance and damping geometries in geodesic space, perceptual qualities in music can be modeled simply and organically using a “reflective interference function" between the harmonic and Fibonacci series. This is then used to explain how musical timbre and harmony are pattern matched recursively as cymatic patterns in the ear and brain.
While this theory deals specifically with the question of music perception, the same universal principles can be applied to explain other natural phenomena. This includes how star systems form, how matter self-organizes into living carbon-water crystals and how self-awareness emerges from physiological resonance. In general, Harmonic Interference Theory offers a unified natural philosophy that merges ancient Pythagorean harmonic science with the quantum holographic model of Bohmian physics and holonomic brain theory.
Here is a 3-part definition of the underlying model - so simple even a cell can do it.
