Greetings, dear Henry. Thank you very much, my dear, for your attention, and I’m very glad you liked it. Basically, it reminds me more of his early sonatas, and regarding the structure, I chose to follow this model because it’s my first attempt, and I wanted to take a somewhat more traditional approach.
Yes, in the recapitulation, I think Mozart was the first to attempt moving to the subdominant, although I’m not sure if Haydn did the same. But yes, we all remember the K.545 sonata for that particular detail. On the other hand, Schubert does this repeatedly — in quite a few of his sonatas, especially in the early ones.
I’ll try to put the same effort and passion into the other movements of the sonata as well. Once again, thank you for your appreciation.
