The problem is that I like all of them and I couldn't choose which one will be the best to start with. I was expecting Op. 49 for an answer, so maybe I should really start with those. Thanks for replying!
Well, maybe a set of variations would be more appropriate... at least that's what my teacher says, and I know she is the best one to give opinion and to choose my repertoire for now, but I am also very impatient.
