It starts with a tense C minor theme.
The second subject at :35 is in E-flat and provides a beautiful respite from the furor.
At 1:57, the exposition repeats.
At 3:57, development begins, based entirely on the second subject.
At 5:09, the recap arrives.
At 5:51, Beethoven does what he should have done in the first movement: the second subject appears in the corresponding major, C Major.
At 6:50, the coda is based on the first subject, but Beethoven throws a curve by ending it not with a bang in C minor, but fading it out quietly in C Major. He had quite a sense of humor, but Haydn wasnt amused.
