Works with no asterisks can be played by advanced beginners.
*) these are harder than the other pieces but a little bit of practice and exercises should help you.
**) these can be attempted by intermediate pianists
***) these consist of pieces of all the 3 aforementioned criteria of difficulty, but the hardest of them would be only as hard as the works on this list with 2 asterisks (the exceptions being Waltz Op.42 and some Nocturnes which are harder than all the pieces in this list, but you can take an attempt if you can handle filigree passages and jumps)
That's it, please correct me if it has any mistakes.
