Beethoven - Piano Concerto No. 1 in C major, Movement 3 (Mother 3 Soundfont)
Beethoven does away with any pretenses of elegance and good manners in this Finale, a rambunctious movement whose main theme sounds like an explosion of energy after everything that came before it.
We also get plenty of Beethoven's sense of humor here. Perhaps the most notable example of this comes at the very end: the piano seems to want to give the concerto an unusually quiet ending and for a moment it looks like it will succeed. The orchestra, however, will have none of it and the piece concludes very loudly instead.
