Sonata's are all boring especially Beethovens. They are too long and boring and never hold the listner long enough to take them anywhere. I dont know why any composer would be bothered labouring over such long music, then again he was paid for it (unlike most composers who write for nothing). I feel sorry for the poor publishers who had to make sense of Beethovens scribble handwriting. Come to think of it I bet half of what we hear was written by the Publisher because he couldnt make out the blobs of ink and weather notes were sitting on the lines or the spaces etc etc. Take a look at the original manuscripts in those times they are unreadable.
BRUH
It was maybe even BECAUSE of the fact that Beethoven was deaf, that he was able to write music of such grand proportions and deep reflection. ALL of his sonatas are masterpieces, architecturally or emotionally.
And no, I don't think it makes a difference whether or not he was paid for it- Schubert wasn't paid jack sh-t, and he wrote all these (beautiful) sonatas: D784, 840, 845, 894, 958-960. Don't forget the 10-minute-long C minor impromptu and the Three Pieces D946, which usually function as a "sonata" when programmed in concerts.
Also, composers wrote "fair copies" of their manuscripts in those days- the material they sent to the publishers was much more readable than their manuscripts, which were essentially "real-time thought processes" full of scribbles, sketches, etc.
Are you sure his sonatas are "boring," or is it just that you don't understand them? What you're saying is against the consensus of musicians- and you write so much about your own experience as a composer/musician! It's like a guy claiming to have all these qualifications to be a historian or a political scientist, who then says "Russia should annex Crimea and the rest of Ukraine and then some lel420yolo."
The more you write these critical things, the more credibility you are losing, and the harder it will be for you to promote your work- especially on this forum.
