Re: Also further thoughts on impressionism
I can understand how much you love sonata form, but it's silly to pretend that organizing compositions into three distinct movements that have nothing to do with each other, where the middle one is slower than the outer two, is an important historical development or in any way the right form of organization. Yes, it's nice to contrast fast bits of music with slow bits of music, but any concert programmer knows that, as does any teenager who's ever made a mixtape. And you can certainly put together a Debussy concert with good contrast in tempos/styles/organizational structures (he's written at least a few things in rondo form, for starters).
You might as well criticize Monet for not painting triptychs.
