There is a great depth to the mathematics associated with music in terms of chord structure and progression, but clearly the brain does not primarily compute frequencies, ratios and sequences when improvising. However, there is clearly a correlation between mathematical abilities and musical talent (or at least musical intuition for those without access to instruments), at least colloquially, and I would imagine it to be true statistically. Why is this? What is it about the way we think of music that is presumably similar to the way in which we intuitively consider physical processes or mathematical structures? Thoughts? Ideas?
