So, if I understood correctly, you guys are against the high articulation of the finger?
My whole technique is based on articulation, counter-movement...
I'm against playing the tones from high (have the finger 2 centimeters above the keyboard-so to play the tone you need not only to move the finger 1 cm down, which is the depth of the key, but also this 2 cm above the keyboard). This kind of playing is much more uncomfortable, unnecessary and produce hard "deaf" tone.
On the other side you can put the finger on the keyboard and at the moment of playing, you just push the key without overcoming "the air space". After you've played the chord, you need to lift the finger up and there you have more options how high you should lift the finger...I think that as much as you lift the finger above the keyboard, the tone is more resonant and more melodious. (but even the high lifting is not possible every time, so don't try to lift your finger after playing the chodr higher than your comfort zone).
In the practice it means that if you want to play soft, forte tone the right way: put your hand on keyboard, prepare all your fingers on the right keys and than in just one hundredth of second you push the keys down and lift your hand up in space...
Hope, it will help. (Also hope that you'll understand me because of my english)
