"Luckily my fingers are attached to my body, and theoretically have 170 lbs at their disposal. Realistically, it is the weight of my elbow and forward in a completely untensed state. I would assume that any pianist was aware of this mechanic."
Oh, so now there is weight bearing down on a relaxed finger? And you are telling me that a "relaxed finger" is going to remain in position when there is an additional force bearing down on it. That isn't going to have the whole hand collapsing and then being dragged off the piano?You are confusing relaxation and COMFORT. As I stated before, I am saying there is nothing to relax FROM- unless you are compressing against the keybed in the first place by involving unnecessary pressure from the arm. You go straight into the position of comfort, in what I am referring to. We are both using the exact same effort to stop the finger collapsing. It's just that you refuse to acknowledge it.
"But not you I guess.There are many relaxed methods, which one are you talking about?"
The one where you literally relax the fingers, rather than simply move into comfortable balance.
"No doubt you are doing it wrong if you came to the conclusion that dropping and bouncing is the best solution."
? Would you please read my posts before making any further replies? You seem to be arguing against somebody else entirely. What I pointed out was that if you follow YOUR explanation of a relaxed finger, THAT would bounce. A key does not settle against the bed unless something is keeping it there.
"First an obvious observation can be made, which is that:
If you aren't completely relaxed, then you have more mass.
If you are completely relaxed, then you have less mass."
This is perhaps the most bizarre claim of 'science' I have ever encountered.
"If I play this chord only using the knuckle and beyond, and you play this chord from the wrist on."
Where on earth did you pluck that from? You post is riddled with these illogical and unfounded assumptions. How about if we both play from the knuckle- considering I never suggested anything about playing from the wrist? Please take the time to read my posts and stop arguing against a strawman.
"And finally, back to the trampoline thing:
A hand which hit's the ground going 10 m/s and bounces back up at 10 m/s has had a 20 m/s change in velocity. Comparing the energy of bouncing to crashing, a bouncing hand (all else equal, i.e not a comparison to my method) has *4 times* as much energy put into it.
KE = .5mv^2.
Double the change in velocity means quadruple the change in energy."
Assuming zero conservation of energy? That's a "bounce"? Did you honestly study engineering? Did you pass? These irrelevant figures aren't even accurately calculated. After contact with the key and bed absorbed the energy (even if it passed zero energy back and the muscles instigated the ascent- contrary to anything I suggested) the energy it would be carrying at 10 m/s upwards would be equal to that it initially had downwards. So these bizarre and irrelevant calculations (that are compromised by omission of countless important factors- eg. a hand can't instantly reach 10m/s upon ascent) ought to shows DOUBLE the input of energy- not quadruple. The equation should accurately contain the absolute velocity- not change in velocity. Where on earth did you study?
