Again, why do I have to reach farther than "the nature of the Gaussian distribution says there will be outliers"?

(Also... "there was only one Mozart" is rather more hero worship than truth. There are many factors that coincided to make Mozart, and I fully expect there have been multiple people since then that have been every bit as talented, but didn't have the same factors coming together. Going into that would be a long, long post about music theory and music history, though.)
