Josiah Green's Symposium presentation at the Mystic Sea Music Festival was quite interesting. He spoke about mathematical relationships in Debussy's La Mer. Frankly, I found the concepts he presented nearly incomprehensible but it seems that others understood what he was saying, comparing the relationships he presented as similar to Mandelbrot equations.
The new field of ecomusicology which he is studying seems to be something we all seem to understand at some level but I also recall that in Statistics we were taught that correlation is not causation. This suggests to me that what we do instinctually may be expressible in mathematical terms but the expression is not necessarily a valid statement of causation.
