Curious! Instead of straightening your fingers over the black keys, why not just keep the finger curved, lift your wrist, and play more into the black keys? If your fingers are curled, they are in a straight line instead of the curve you show when playing a 5-finger C-scale. If they are curved, rather than straight, you have more control to keep each note even.
Thank you so much! I hope I will be able to learn this peace finally. I feel like I have achieved something big if I master this piece 🙂.... it has been on my bucket list for many years. But until now I have avoided fast pieces because I simply can't move my fingers fast enough. so hopefully I will be able to improve thanks to your tipps
