But that's split between the fingers and the mass of the arm exists to stabilise due to inertia.
I appreciate that it probably didn't read this way, but i was certainly not trying to suggest that each finger must individually supply a full KG of downward pressure.
rather that in order to supply a total pressure of 1KG that it would be wise to use the weight of the arm more so than to over exert fingers.
---------------
That aside - nyiregyhazi, you seem more physics knowledgeable than I - perhaps you can clarify the relationships between weight, velocity, and force..
since in my mind if, the touch weight is 50g, then i should be able to displace it enough to make a sound with lets say 55g
- but thats talking about a free weight falling into the keybed (as with stacking up some pennies) and its starting on the key - fingers on the other hand could supply 55g of
weight at a higher
velocity - which would result in greater
force applied to the key - but perhaps does not require more strength so much as simply the ability to move faster..
...this all with out going into how varying arm weight effects the velocity of the key/hammer without any alteration to the fingers motion..
...or the factor that I was thinking about with this thread, - that poor technique results in added and unnecessary fatigue in many places
