<DIV><FONT face=Arial size=2></FONT><BR>The story which I heard is =
from Barney
Ricca, former PTG member, <BR>actually a physicist at one of the Texas
universities. At the '95 <BR>Albuqueque National, he was summarizing the =
conventional wisdom, <BR>saying that in the initial impact, this wave =
form in
the string , <BR>viewed axially, would be purely vertical. This would =
last for a
short <BR>interval (proportional to the total sustain time) until the =
string's
<BR>energy would spill into the other (infinite) modes, to remain stable =
<BR>in
that chaotic "omni-mode".<BR>Bill Ballard RPT<BR>NH Chapter, =

<DIV><FONT face=Arial size=2> Bill, et =
al.....
I've thought about this phenomena many times, and I was really hoping =
someone
would put a definitive answer out here on the list, but I haven't seen =
one yet.
</FONT></DIV>
<DIV><FONT face=Arial size=2> I've noticed this on =
a couple of
Yamaha's, and the funny thing about it is just that, going down into the =
bass,
you get to a point where one string starts a very faint yow-yow =
longitudinal
wave thingee, the next note is worse, the third note is really =
noticeable, and
then the next note not so noticeable, and the next note it's almost =
gone.
I just thought it must have something to do with the strike point =
crossing a
node, or something. I don't know what to do about it, other than to say =
that
almost every interval where we can play two notes together will produce =
beats
somewhere, so it shouldn't be bothersome in such a lively "vibrato" =
instrument.
</FONT></DIV>
<DIV><FONT face=Arial size=2> I'd still like to =
know how to do
something about it, though. </FONT></DIV>
