Imagine how it must feel to get something so right that there are no flaws, no deviation from expectations, nothing but pure unadulterated perfection. Is it even possible? Is perfection a myth? Imagine for a moment Beethoven's original score of his magnificent 9th symphony. Here's what it looks like: Perfection would seem to be following every note and notation exactly as written. Perhaps something best left to a machine trained to never deviate from the score. And yet I doubt that Beethoven's 9th as rendered by a machine would be perfection. In fact, I'll bet we'd probably scrunch our faces at what we heard. Perhaps perfection is like beauty, in the eyes and ears of the beholder.
