This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment 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 Ballard RPT NH Chapter, P.T.G. 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 Kevin E.
