Absolutely. Consider me corrected. I daresay there are also plenty more
different and wonderful theories to be had in addition to these.

As it should have been easy to see from recent posts, I was challenged to
present a URL, or other authoritative source to what I was saying. I
answered the question, but it is apparently not proper for me to ask the
same of the two proponents of the other theory. And yes, the differences in
perspective are quite evident.

As is, and does, the theory the three of us propose.

I see no purpose to it. The fork will move the wire, slack or otherwise,
and the moving wire or rod will move the soundboard - producing a faint
sound, as you indicated. I don't think the handle of the fork is moving as
a result of an internal stress wave any more than I think the bridge and
soundboard are. So this test proves what?

Excellent suggestion. Consider it acknowledged.
