The numbering of the Chopin nouvelles etudes is apparently not completely universal. My edition (Paderewski) lists the Ab major etude as the last one, so I believed it to be no 3. For this reason I overlooked Monica's post of it, confusing it with her earlier post of the Db etude which is number 2 in my edition. Only recently did I discover the facts. I want to post this anyway, with apologies to Monica for crowding this piece. Monica articulates more clearly, I go for a more dreamy and blurred approach though the tempo and main ideas seem very similar. There are several quite different interesting interpretations on youtube, check for example the ones by Rosenthal (a pupil of a pupil of Chopin) and Cortot (who plays this as number 3).
This etude turned out much more difficult than it looks (and hopefully sounds). The main problem for me is not the polyrhythm but rather the voicing of the RH chords, one mishap there and much is ruined! It is also a test for the RH pinky who plays almost all of the melody.
Again apologies to Monica, and a promise that my next post will be something no one ever played before!
This recording is single take, there may be an occasional error but I hope not too many.
