I've noticed, that many people are hitting keys, instead of just pressing them. It kinda looks like that before they press the note, they lift the finger a little bit, same as if you tried to hit a nail with a hammer.
Is this correct? Should I try to practice this, or instead just try to leave my fingers lying on the keys and just pressing them?
This looks a little bit like the exact opposite of typing on a keyboard, where I'm trying to just move around the keys and press them, without hitting too hard, which makes me type pretty fast (450-600 characters per minute). But I guess piano might require a different technique.
One funnny thing worth noting, after I finish playing the piano, I find myself typing on a keyboard much faster :)
