Mathematics? It's all just life.

"Despite the fact that J.S. Bach was not widely appreciated during his lifetime, among those who knew music well, his reputation had spread. In the year 1747 he was given the honor of visiting the court of Frederick the Great at Potsdam (May 7th and 8th) where he brilliantly improvised a fugue on a difficult theme proposed (and composed) by the King (himself, an amateur flautist). Stories of that amazing improvisation (a six-part fugue) on a theme conceived almost to defy the possibility of such improvisation, have become legendary and have been likened to a man playing a hundred games of chess simultaneously and winning. It was a feat of unparalleled skill and musical genius."

That fugue has been described as almost mathematically impossible for a human mind to create.
