The neural symphony

"It’s pretty obvious we can all perceive music as such and thus have something in our bodies which has the specific function of extracting and interpreting information in a musical form. To explore this notion further, we should first look at what happens in the grey blob that lives inside our head, called brain, when we listen to music."

Symmetry

"Music is symmetrical. Tempo and rhythm are the obvious proof for this. Symmetry is very unusual when it comes to naturally occurring phenomena and it’s weird to see, or in our case – hear, it while you’re strolling through a forest, for example. Rocks and plants, and clouds, and rivers are almost never symmetrical. Animals, on the other hand, are. If something is symmetrical it’s most likely alive and things that are alive are definitely things you need to watch out for. In nature, symmetrical stuff will usually be a) something you want to eat; b) something that wants to eat you; c) something you want to have sex with. This would mean that animals, including humans, are likely to have somewhere in their genes a strong instinct to pay serious attention to symmetry. If this is true, our predisposition to music has just become more logical in an evolutionary sense."
