A refreshing Ph.D. in Music Theory, Isaac Malitz, actually has started posting on the Theory Society Chat Line about how notes furnish only one of what should ideally be several possible models for music. He uses a model of his own devising that has to do with meaning.
Tonal Refraction is an alternative model that does not pretend to model music but rather the experience of musical elements, an experience directly analogous to life, thus subject to infinite variability.
None of the terms of Tonal Refraction is fixed, not the colors, not the spatial aspects representable on the grid: everything is fleeting, subject to change depending on a multitude of ever-changing conditions, needs, etc. Check out the website: www.tonalrefraction.com
