Oh, I'm just also curious: On a scale of 1 to 10 in difficulty, 10 being most difficult, what would you give the Polonaise-Fantasie?
Well, I guess either 1 or 10, depending on whether you can play it or not. The logic here being if you can play it, it is easy, and if you can't then it is impossible. (This I think I got from a Bernhard post from the archives, and it is completely logical). Given that I learnt this piece just recently and I can't (yet) learn some of the Studies I wouldn't say Op.61 was Chopin's hardest piece. Overall, there are pieces I would find much harder, but this is an impressive work when played well, and a very beautiful one too.
At the moment I'm trying to learn the Chopin Polonaise-Fantasie in A flat major. On the last part, starting measures 242, how do people nail those chords cleanly and voice the top effectively?
From bar 242 Chopin seems to get louder and louder, so although it says 'forte assai' leave something in reserve. Practise at pianissimo, bringing out the melody at mezzo piano - this will save your fingers! Bar 244 is probably the hardest, and then bar 248, so work tirelessly on the right hand in these bars. Get the conjunctions between the chords as slick as you possibly can, first in small groups (just two chords?), and then in slightly larger ones, etc. Do that anywhere where you have difficulty, but start with those bars. Simply put, it is just a case of getting the movements of your hand working properly - it is perfectly possible.
Actually, from my point of view, at least, I just lied. I found bars 250-51 the hardest - I've still not nailed these too well. I'll be using the procedure mentioned above. I don't think it is possible to play these bars at full tempo - not for a mortal at any rate.
Good luck.
Richard.
