This is a great discussion! I go back to the idea that music structures have a basis is neuro-physiology, and it is in some way measurable. It is probably in hair cells, respiratory rate, hormone production, and all areas of neuro-chemistry. I'm not scienticically traines, but I would be very curious about the studies in brain imaging. I wonder if it is cross-cultural, related to age, and the differences in brain disorders like autism. Can you imagine the ramificatons if science developed a "data base" for music structure that could be used as a "baseline" for neurological disorders?
