I don't know why the difference in sound. I also don't know why, if the
energy goes directly through the bridge without moving it, and into the
soundboard which then moves, why touching the fork to the exposed edge of
the soundboard won't produce the same tone as pressing it against the top
surface. Perhaps you can explain it to me. 

I don't refuse to absorb it John, I don't think it is correct.

I asked because I can't seem to get a simple question of my own answered
along these same lines. How small does a movement have to be to be non
existent?
