What do you base this on? Does anyone know the origin of this kind of =
thinking?


Not even Steinway marketing would agree with this:

"... the equally erroneous theory that sound "vibrations" in some way =
travel transversely across the soundboard. But, as has been shown here, =
the movement of the board is that of the movement of the strings, up and =
down in the case of a grand, backward and forward in the case of a piano =
of vertical construction."

Hold onto your hats: I agree with Steinway!
