How would you go by putting the fingers for the 12th - 13th bars and 40th - 41st bars, especially for the last 8th beat of 12 and 40?For 12 I use RH: 1 3 5 and LH: 5 2 1For 13 I use RH: 1 2 5 and LH: 5 2 1For both 40 and 41 I use RH: 1 2 5 and LH: 5 3 1
this many give you a little insight
Your fingering choices are standard for these passages. To make this etude playable, you have to bring out the tune in the RH thumb and the corresponding ringing high notes at the end of each "wave." This is all clearly marked by Chopin in the score. Do exactly what he calls for. In between these high points, make sure you are not tensing. Use "tension" (better words: "muscular contraction burst") only for the arm weight needed to bring out the tune and the, well, "breaker crashes" at the top of each phrase.If you concentrate on the music in this wonderful etude, you will find that it is much easier to play. if you concentrate on the technical challenge, you'll sound like a cement mixer at the bottom of the Mississippi River.The choice is yours. Have fun. I don't think any of Chopin's Etudes are more pianistic and fun to play. Work it up very slowly and make sure your movements are fluid. Move your body (right, left, right, left) with the rising and falling passages. Keep your trunk behind the notes. Don't sit stalk still and just move your arms. Really feel as if your riding those waves, sailor! You'll never get it up to speed if you don't.Hope this helps.p.s. to the poster who thinks the spans in this piece are so large, look again: they're only octave spans.
