I have an engineering = backround so I have to model the situation and analize. Here are a few = postulates FOR the theory.=20 For the hammer to create a louder tone, the hammer must have a higher = velocity when it hits the string and therefore when it leaves the jack. = In the static world the knuckle leaves the jack before the key hits the = punching. Obviously the flex and delay (compression) in the system = allows the key to contact the punching before the let off point on = harder blows. The flex of each particular piano will have to be taken = into account. In pianos with less flex the effect/difference will be = less because the delay not being so great, let off will occur before = deacceleration has a chance to affect to speed of the jack. With a = softer punching, slow down of the key begins sooner and takes up more of = the stroke. As the flex unwinds through the system a gradual and early = slow down of the key will result in a decrease in velocity at let off. = Just as with the teeter totter, as you take up the landing with your = legs, you control the launch velocity of the kid. Andre works on a lot of large grands with big keys and lots of mass =3D = more flex/delay. kpiano ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
