I can't seem to find non-harmonic analyses of Beethoven's sonatas. And I'm not a classical music analyzer. That makes it hard to write a sonata in the style of Beethoven when I don't know what Beethoven's style is. I've been told that I don't have to go extravagant, that I can just write something simple.
Well I tried writing a simple sonata years ago and I managed to write 1 movement, just 1. And I played it and I know what composer it sounds like more than anything else. That would be Mozart(probably due to the Alberti bass and major key in the unfinished sonata). I know that early Beethoven and late Mozart sound similar but as Beethoven wrote more works, they diverged to be more towards Chopin's style than that of Mozart.
Somewhere in between those 2 is what I would consider to be definitely Beethoven's style. Take his 5th symphony for example. It doesn't sound like a late Mozart work nor does it sound like that of Chopin or Brahms or any other Romantic era composer. It sounds like Beethoven. But what is it about Beethoven pieces that makes it Beethoven's style?
Is it the use of sudden changes in dynamics often? Is it the coda being like its own section instead of like a tag at the end? Is it the use of 1 motif throughout a piece(which I particularly notice in his 5th symphony)? Is it the common use of minor keys? Is it all of these?
