Listening to this got me thinking: In the days when this was recorded in cuneiform on clay, mastery of anything was a form of magic. Only a genius could have created this piece or performed it, because they didn't have the same kind of rigorous science-based educational system. But since the advent of the scientific method and applying it to our educational system, we have learned how to partition masterpieces (art, music, stories, structures, and so on) into understandable components, analyze them, and reproduce the effect they create in the mind of the audience.

Now anyone with sufficient interest and patience can learn the theory that once produced what we believed was actual magic, and with practice and a lot of effort can perform such a piece and maybe even come up with one that has a similar effect. It's like Hogwart's for everyone; we can all learn the magic, if we work hard enough at it. I suspect this is why creative genius today is so hard to pick out from a crowd of art - anyone can look like a genius. But it's also why we recognize true genius when we do encounter it.
