something to think about later

So music is maths; visual symmetry is maths; what the eye finds pleasing is also in the numbers, perhaps the ratio of the hues. What about touch and symmetric textures?

What about notes from a different key that fit? Is this just the suggestion of a pull, a link between two different patterns? Or in some cases, so out of sync with the pattern that the ear is pulled towards it, and the mind keeps the interest in the piece. Are we instinctively aware of patterns, hard wired into our brains?
