The first movement gave me a little trouble but after reviewing some old textbooks I think I'm going with my hunch: the first movement is in Rounded Binary.
The A is from mm. 11 - 78. It begins with an introduction from mm. 1 - 9. The A section is primarily in g minor until the modulation to Bb Major in m. 55. The piece then repeats moving to the B section from mm. 79 - 127. The B section begins in a different key - in this case c minor in m. 79 and f minor in m. 101. In the B material there are parts of the original A music used within the parts. It is not that it is developed on but rather just used in a different key. The return of the A section is in m. 128. It is back in the the original g minor key. There is another modulation / key change that occurs in m. 168 and a codetta that starts in m. 193 after the PAC in mm. 191 - 192.
The second movement is clearly a theme and variations. In this movement the themes are divided quite easily as there is a stricking contrast in the keys, texture and style. The piece begins in E Major. The main theme is introduced right in the beginning. Through mm. 1 - 22 Haydn writes starting in a major key - then at the double bar line changing it to a minor. He finishes the Variation I in the major key. We see Variation II introduced in a cminor key starting in mm. 23. Variation III begins in m. 38 back in the E Major key. I believe that Variation IV occurs in the jarring chord in m. 45 to the end of the piece.
Well this is my anaylsis - could be right could be wrong!
Over and out -
The one and only- Canada.
