OK people, here's the first analysis. Feel free to disagree w/ me (as always, at your own peril). Piano Sonata no. 52 (Haydn at his oldest and wackiest):
As with almost all piano sonata first movements, this one is clearly sonata form. Theme I starts right off the bat in E-flat major (m. 1) and lasts until the PAC in m9. We then have a transition lasting from mm. 9-17 that modulates from E-flat to B-flat major. So far so good? Theme II begins in m. 17 (B-flat Major) and lasts until the PAC in m. 33 and includes a little modal switch to b-flat minor in m. 29. Haydn then includes a closing theme that lasts from mm. 33-40 and then a codetta from mm. 40-43.
The development lasts from mm. 44-78 and goes through keys C major, F major, g minor, c minor, A-flat major, back to c minor. There's a truly jarring modulation to E major in m. 68, and finally the retransition in meausre 77 that leads to the recap in m. 79.
The recap is really pretty straight-forward. Theme II begins in mm. 93, and the closing theme begins in m. 104.., and there's a codetta from mm. 112 (middle of the measure) to the end. The entire recap is in E-flat major, of course.
So, that's what I want you all to do this semester. It doesn't have to be polished, really, but please give the form concisely with key areas and measure numbers.
