Key Rebounding Technique On Piano

Lately i have been trying to practice several pieces that have plenty of octaves and chords.I have been following the advice of always having a good structure in the hand. Lately i wanted to integrate some key rebounding technique.Forgive me if i dont explain this well.What happens is that i let the piano keys raise my fingers aftair each stroke(i leave fingers on the keys and i can really feel the weight of the mechanism and key!). I find that this helps me a lot to have the hand near the keys and it allows me to have minimum tension.However if i really want my fingers to be raised by the piano keys and not by my own muscular effort then i have to let my hand structure collapse just a little and the hand to be a little like it is limp.If i let it in the way it is when i stand on the keys then i feel like my "skeleton" fingers are too heavy to be lifted by the mechanism of the key and while i do not feel any tension and i am feeling ok, my fingers keep the keys being pressed down (the power of a properly setup palm with correct structure seems to be very high) Actually it helps me a lot if i am thinking i am leaving the key but then suddenly i decide not to and stay on keys. Am i doing something wrong?Is this technique correctly or is it something that i should abandon? Forgive me i am saying something that is very wrong. Best regards UPDATE:actually i wonder wether it is ok to say that "fingers are lifted by the key".actually i let my fingers remain on the key,but the key is lifted without me using muscular effort but rather as if the fingers are passive and boneless and like they can no longer hold the key and the key is coming up rebounding with the fingers still staying on key. Update 2:I think i found what i was doing wrong,i was playing with a rather low wrist position with flat fingers and it was easy for my structure to collapse if i didnt pay attention.After i returned to a more natural hand position with fingers having the normal curl,and without allowing my knuckles to collapse then i managed to have better results.

Hi Nikodr, I would like to answer to you but i think prof. Alan would've done it way better than me.He is on tour now and will be back in couple of days,so i am sure he will answer your question soon. Jovan

dear nicholas, What you describe is really great! It is actually almost word for word what i have told many of my students to do - this is uncanny! The problem you describe is valid, and it has an understandable cause. You describe one way of solving it; I would do something similar but describe it a bit differently. If the key is not lifting your finger back up, simply try to feel as if air is floating your whole forearm gently up, and also the center of your palm. It's the 'helium balloon buoying' feeling. Do this by degrees, as if your whole hand-arm is a deflated balloon and now some mysterious air stream is coming in and inflating it, and try to notice the exact moment when the 'wieght' of your finger diminishes to the point where the key now raises it. This can be fascinating and very instructive for the inner feeling of moveability in your hand. It helps you find the sense of relaxation that is not DEAD but vital, moving and empowered. best wishes, AFF
