Yeah, good fingering is mostly what I'm after...I'm also working on Prok 3rd sonata and the edition I have has absolutely NO fingering. It takes me twice as long to devise my own fingering.... In any event, the Henle publication of the Ballades is really quite HORRIBLE. I'm sure some will disagree with me, but the pedal markings are COMPLETELY unintuitive and don't make any sense at all. Everyone thinks Henle is the end all be all publisher when it comes to music, but I'm seeing more and more that they really are quite poor in a practical sense. I will go with some of these other suggestions, or maybe just stick to dover.
Don't get the Schirmer - you can't understand a bloody word in the notes!
I heard Perahia is working on a new edition for Henle.
- no editing, only original composer markings, allowing you to use appropriate fingers for yourself
What about the urtext from Konemann Music, Budapest? I think it's an attractive edition.
