Yow-yow-yowing bass strings

The story which I heard is from Barney Ricca, former PTG member,=20
actually a physicist at one of the Texas universities. At the '95=20
Albuqueque National, he was summarizing the conventional wisdom,=20
saying that in the initial impact, this wave form in the string ,=20
viewed axially, would be purely vertical. This would last for a short=20
interval (proportional to the total sustain time) until the string's=20
energy would spill into the other (infinite) modes, to remain stable=20
in that chaotic "omni-mode".

    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.=20
    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.=20
    I'd still like to know how to do something about it, though.=20
