"Shock wave effect.'" was "fish"

[gordon stelter]

Terry,
     The vibrations of tuning fork tines travel down
the stem through this sort of molecular, " chain
reaction ", shock wave effect: compressing and
releasing the atoms from compression ( elasticity ),
and even when the exterior of the stem sides is
supresed from vibrating by our holding it. This same
shock wave travels from a tiny contact point on the
ball at the end ( hardly large enough to move any mass
of material, and not really coupled mechanically to
anything it is just resting on )and these then spread
out into ever wider waves until some portion of the
material they are traveling through vibrates in
sympathy with them, and agitates the air physically,
resulting in another shock wave which our eardrums are
agitated by, resulting in what we call  "sound". Why
is this notion so vehemently rejected, by so many ???
( And please do excuse me if I am mistaken in
considering you among them. )  The denser the medium (
more tightly packed molecules and atoms ) the more
rapidly the shock wave travels, as less atomic
material is freee to be "jangled" against itself, 
causing energy absorption through molecular friction,
which is observed as "heat". 
     Sound ( shock waves ) travel faster in water than
air, for example, because the density of the water is
greater. This is a  basic fact of physics.
     No disrespect intended---your skills as a
craftsman are utterly stunning and truly humbling----
but why should all of these basic facts of physics be
refuted, when the piano is concerned ?

     Or am I misinterpreting this debate?

     Respectfully,
     Gordon


P.S. Dear Sarah,
     I suspect that you can refine my definition, and
kindly request that you do so.
