Chopin Etude Op.10 No.8

[pianovlad1996]

Can you help me with some problems in this etude? I started it one week ago and I have a few problems that are important when I have to play the etude in tempo. First, I feel the fingering in measure 47 is hard and unusual for my hand: 1235-for the first group, 1125-for the second and 1235-for the third and the fourth. I tried thrice to play the groups in a more animated tempo than the previous (that was 40-50 bpm) and noticed it's quite hard. My teacher asked me for 1215, 1125 and 1215 (2x) but it's more difficult than the previous. Can someone give me a good advice with this fingering? The second problem is in measure 15. The span 2-4 is too much for me and I can play equally every note. If you guys can help me with those problems I'll be very grateful.
Love,
Timea

It's "hard and unusual for any hand"!    I don't understand this 1-1-2-5 in the second group.  You mean, sliding from a b-flat to a c?  I wouldn't advise it.  I think the problem lies in the the interval from the 3rd finger to the 5th.  It's a big stretch and the hand tends to tighten up when you do it.  Consequently, the whole passage is played with a tense hand.  And tense hands mean slower playing, pain in the arms, etc. etc.  The fingering possibilities here are quite narrow.  Unless you do 2-1-2-5.  I would suggest practising in hand positions.  The first is 1-2-3  The second is 5-1-2-3 then 5 then 3-2-1-5 then 3-2-1-2  The same for the next 3 measures.  Yes, you can play a black key with your thumb!  The important thing is for the hand to remain loose and relaxed.  Work in hand positions - and get each group up to speed.  Now, practisie landing on the first note of the second group.  Begin the second group with that very note and land on the beginning of the next group.  Again, get it up to speed.  Go back and do the first excercise again.  Now, play slowly with the metronome, but concientiously lift the hand impercepitibally before the 3-5 interval and don't stretch the hand.
The other measure isn't 15, I think.  Aren't you talking about 14?  It's the exact same problem.  The stretching of the hand if you play 5-2-1-5-4-2-1.  Try 5-1-2-5-4-1-2.  Here again, you have to keep the hand relaxed and not stretched out.  It should be like putty that stretches when it has to, but snaps back into a relaxed position.

Thank you for your advice. . I found it very useful. I couldn't respond to your message because of my buisy program. Now another question will be at the middle section with the semiquavers in the both hands. Should I use descendent and ascendent arm movements or play them without any poignee & arm movement. I'm confused...  And for the other etude (Op.25 No.11) how should I use pedal at the final section (coda) because chromatism makes pedaling sound dirty. Can you help me with those problems?
