tszulc90 One other thing, why is your RH wrist hanging down? When you reach for the black keys, your wrist looks good. Consider playing the white key passages the same way.
WieWaldi I forgot to answer this as I was focused on something else in the thread. Thank you for pointing that. Yes, that's why I like to record myself. I noticed this some time ago I tend to lower my right hand with these 16th notes. I must do some work to fix it.
Two year beginner here, too, so take what I am about to say with a grain of salt. I wonder if this has to do with being afraid of letting the fingers uncurl and play between the black keys. I had this exact tendency at the end of my first year of self-study, and this problem in technique is one of the main reasons I got my current teacher who corrected it and more.
When one play only at the front of the white keys, because our fingers are of different length, some will have to curl more at the 1st and 2nd knuckle. Playing faster passages often requires finger tips stay closer to the white key surface, thus may exacerbate the need to curl all fingers to make the finger tips level with key surface. As fingers get curled and raised, the metacarpal joint becomes flat, and when metacarpal can't go past flat, the wrist must drop. I've seen fast trills being played or taught to play this way. However, the passage here is not that fast to requires this technique, plus it looks awkward because, unlike trills, more fingers are being used here.
If you uncurl your fingers, to their natural shape as when you loosely hang your arm and hand fully down the side of your body, then lay that hand shape on the white keys, and note the position finger tips naturally lands on the white key, some finger tips may fall between the black keys (if you also keep your thumb's tip on the front edge of the white key). Play the keys on there positions, without curling the longer fingers up or back. You will not need to drop the wrist. Instead, you will be able to, and must, let the wrist relax and loose. Try this. Talk to your teacher about it.
@tszulc90 You played the piece very well, with steady rhythm, accurate, and articulate. Well done!
