Well... As long as you can play it properly, why not... But if you can't, play something else for the mean time, then try it again after a few months

... I was just playing Bach 2 part inventions when I tried 10-12, and surprisingly, I was able to play it quite properly, then I kept on pushing myself, Rach prelude in g minor, Scriabin etude... was it Db, i forgot, then Chopin Scherzo no.2. Afterwards, I became too ambitious and went for Liszts's mephisto waltz. I was really struggling so I set it aside and went for some other pieces: Liszt's Waldesrauchen, Chopin Ballade No. 1, a few chopin nocturnes, then, when I went back to it... I managed to be able to play it... Not properly yet though... working on that

I just want to know... how many people are going to kill me when i say that I used to call Chopin's Etude Op.10 no.12 Revo etude? I just realized today (while reading posts) that calling Chopin's works by their invented names is actually a no-no...
