 Ron,
     It being late I will be brief.  How can you  claim that a slack wire, lying on
the ground or otherwise, will energize  when attached to a tuning fork, a
soundboard by transverse motion of the wire when there is no tension in it? .  I
would like to ask Del the same question as his reponse to this was that the fork
was not the same as a piano string, that not being a point at issue.  I am baffled
and mystified by this.  A good evening to all, pro and con, and a Merry Christmas.

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?
