Here is my belated response to a question you had asked earlier – about sonata and order in chaos.
“ok, good: so
where can I find info about beet and the sonata, b/c
this point is part of a story I'm writing and needs to be better
thought about -- b/c
why not have no pattern, always new stuff, why is pattern good in
itself? I know I sort of already answered this, but I'm not
convinced I'm right. Why is repetition and sameness good? Why is a
false order -- b/c life is chaos -- imposed from without by the
artist important? And how can we judge some false orders better than
others, as being more lifelike and real and true to nature, when in
fact all patterns imposed from without are false, so it's all false?”
First, you get pleasure from hearing the good melody again. The simple pleasure effect. And the fact that you’ve already been “exposed” to the original melodies. Now hearing them in a new way (the recapitulation is in a different key) creates the pleasure of novelty, perhaps even growth. You are wiser now in other words. It’s all abstract of course, but it works. None of this would be possible without first establishing a baseline from which a development and recapitulation may follow. Imagine taking the ending of Sonata A and switching it with Sonata B. Same chunks of music. But none of the aforementioned benefits.
That is your answer. Yes, it’s an abstract construct, but yes it works.
Why some false orders are better than others I suspect is purely empirical.
