prepared key attack

[nick]

Does anyone care to add their opinion on prepared key attack for scale like passages in general? I am experimenting with slower practice for a period of two weeks, and noticed how much more prepared each finger is on each key before key depression, and wondered if this is the best way in general to practice.
Thanks in advance,
Nick

I am doing that right now... and it seems there are different approaches to the way to do it.
One of my friends draws a vertical circle with their fingers in preparing, touching and departing from the key (touching all the surface of the key from the moment of touch untill the raising from the key). I am touching the key with very much attention to balance and relaxation.
I also do a lot of stacatto work, non legato and "half-legato" (very close to legato, but gives a sense of brightness to your playing... horowitz sais more on this at this article: https://users.bigpond.net.au/nettheim/horowitz/horo32.htm
Hope this helps a little,
Bitus.
