Do you know physics??in hschool.
The word momentum = mass X velocity .
Not so. This would mean there is no momentum for a linear motion. Would be really hard to play like that.
In classical mechanics, momentum (pl. momenta; SI unit kg m/s) is the product of the mass and velocity of an object.
sorry Chris, Its velocity. not accleration.. . my memory mistake.
we dealing with force F(piano touch)=mass X accleartion; and momemtum P= mass(M) X Velocity(V) .
thereforfoe Force =(P/V)X accleartion. The mass is replaced with P/V. So piano playing is effected by "linear motion"-speed and accleration. This applies to force(f).
So by looking at the equation F= (p/v)XA
By all means, if you had a bigger build or bigger mass, naturally (in theory), you would produce a stronger tone as compared to a smaller person where he/she have to work harder eg she or he can either increase the accleration of the finger storke or increase body mass(get fatter
Or think this, with FF playing, you need a balnce between weight(natural fall)-massXaccleartion.
But with reduced accleartion to zero, but a constant linear velocity, you will get a softer tone.
Does this make sense now Chris??
