curiosity along those lines concerned tuning stability, and
how<BR>dimensional change in bridges and soundboards, or how
much<BR>rendering across a bridge accounted for what we hear in
real<BR>pianos. I expected a moderately accurate proportional<BR>indicator,
rather than a three decimal point absolute. List<BR>discussions seem to be
thick with binary all or nothing<BR>arguments, but I live somewhere well in
between.</BLOCKQUOTE>
<DIV><BR>Ron,<BR><BR> I think I may have found a kindred spirit
:)<BR><BR>Beyond my simple thirst for knowing why, my interest here lies<BR>in
trying to figure out what I am actually doing when I find a stable<BR>resting
place for a member of a unison. My goal is to distill a belief <BR>based on
reason and evidence rather that myths that somehow<BR>seem to work, as if by
magic.<BR><BR>We are not scientists, but I feel that much can be gained by
<BR>taking a few minutes and pretending we are.<BR><BR>For me, the issue of
pin movement is a good place to start, <BR>although it is only the tip of my
current set of ideas for<BR>real-world experimentation.<BR><BR>If you would
like to share ideas more fully, I would<BR>enjoy continuing this discussion
through email if <BR>you want.<BR><BR>Let me know.<BR><BR>(and as far as the
original question goes, I have also posted<BR>it on a physics forum, so I will
let you if they have anything to<BR>say to clear things
up)<BR><BR>Thanks,<BR><BR>
