Autoregressor - 11 by Greg Baker

I can't say that this is a particularly beautiful fugue for organ -- there's not quite enough going on -- but you could imagine hearing this being played in a church during Mass or something.

Which is interesting, because (mostly) this wasn't written by a human being. This was composed using the "Bach Autoregressor" in AWS DeepComposer. I gave it an initial melody -- of which there is now no trace in the final composition -- and let it rewrite and rewrite until it got to the piece that you hear now.
