Actually, I would say that Fur Elise is less paint-by-numbers then his symphonies, but to each his own. None of that would make it on my list of music I’d select if banished to a deserted island.
I wonder if Bach would have done things differently if he had Dorico. Most of his stuff was written quickly under the weekly pressure of his church commission. Even without Dorico and all that time pressure, just about everything he did (that survives) is elegant, and hard to find any angle for improvement. I guess he threw away 100 times as much music as most of us will ever write. Perhaps with the benefit of Dorico and good playback, some of the discards would have become survivors.
