First Movement

Last week, unable to stop listening to Schubert’s Sonata in B-flat Major, I took the next logical step. I found the music online and am now trying to learn this amazing piece.
As typical in an endeavor of this sort, I come up against my impatient personality and some basic questions: How many mistakes can I tolerate? How correct must I be? I have no teacher to suggest fingerings and dynamics. I’ll rely on YouTube and my own rusty technique.
The music has been in my head since the concert in Providence. Now I must get it into my fingers. I’m starting small, a page or two at a time. If I can even semi-master the first movement up to the repeat by the end of the summer, I’ll declare victory.
