Necroposting because I'm surprised so many people are saying that no. 2 is harder than no. 1. No. 2 is quite easy as long as you play the whole piece delicately and very, very, very, very slowly. (as long as you can be musical about it) and those runs (48 and that other one on the same page) are nothing. No. 1, meanwhile, has impossible octave jumps in the Piu mosso section that I don't think I'll ever be able to fully get them down. Since the whole Op. 27 No. 2 is slow, there's not any difficulty with that aspect which I completely struggle with. Must be why I keep learning the chopin nocturnes rather than other music I enjoy much more, such as the mozart/beethoven sonatas
