Thanks for your responses.
Yes, I don't usually like the development-recap repeat either but I can see where it can help balance the form. The exposition repeat doesn't always bother me either.
Mozart sometimes throws so many themes at you (I think in his k332 sonata first movement, up to seven) that you sense little thematic growth in the exposition and you don't mind hearing it again to assimilate all the material.
In your case (and in some beethoven) the developmental drama begins right away. Your whole exposition derives from two short themes and it's very well done. However, it creates such a trajectory in my mind that hearing it all again right after it finished the first time does feel like repeating a battle. It doesn't kill the movement for me, just makes it a little less than ideal.
Yeah, at bar 65, the exposition ends in the high treble and the development commences in the same bar. I think the first few bars of the development takes the place of an exposition repeat in terms of creating suspense. Appasionata's exposition is long and thematically compact. In the Walstein he does repeat the first movement's exposition but that exposition is more thematically rich.
Yeah, music is a personal journey and each person's style will evolve as he writes. Mozart had some interesting ideas too for the recap. He sometimes inverts the order so the themes reoccur back to front after the development. The whole form then becomes symetrical about the development. He was also fond of changing the mode in the recap, varying the melodies or interjecting new material somewhere.
I absolutely agree!
It's all about balance.
If you go too far on the repetition axis or too far on the variety axis you might fail.
In one case because it gets boring, in the other case because it's incoherent. It's the same as in speech or oratory.
In my own attempts at composition, I don't care too much about pursuing unfamiliar harmonies but I'm always thinking about form. That's one's primary means of guiding the listener.
Anyway, great reading your posts and keep up the awesome musical writing.
