Thanks your answer, Ron. I'll try to snip so this doesn't meander. >I've been wondering myself if a hard blow CAN drive a string up a bridge pin, or if it's exclusively a humidity swing thing. Well, are false beats worse in the eastern U.S. where humidity changes are drastic, or do they also happen in places like Montana and Arizona? If people can clean up false beats in dry climates by seating strings, then something other than humidity is at work. Hard blows seem a likely place to look. >and a tuned string creeping sharp as it is pulled back through from the tail if it was pounded in too hard and not set well. True! I've seen that too. That would imply that the back length is creeping through the bridge pins. But could it also creep sharp from excess tension left in the front duplex? The bridge might not even be involved. >It seems to me that a string rendering through the bridge would tend to seat itself by virtue of downbearing once the stagger friction is overcome and the string is sliding. You'd think so ... has any intrepid person tried finding a string that is riding up a pin, (feeler gauge, etc.) then letting the pitch far enough down to be sure that the string has rendered through the bridge (i.e. just to the point where the back length has changed pitch a little), then pulled it back up and seen if it has seated itself? (Not before a concert, natch!) >You can pound a string flat (pitch <G>) and have it come back up somewhat (I've seen it in about octave 6, where all the weird stuff happens) without touching the tuning pin at all. Octave 6 (well, the top part of 5 also), musically the most important, where stability is hardest, where false beats are the commonest and the most annoying, where tone is the most critical and the most difficult ... Is there some reason why all the problems happen in the same area? Sometimes I wish the front duplex could be eliminated, and agraffes could go all the way to the top. Or is the trouble more from being out in the middle of the board? >If a pianist CAN unseat strings it would pretty much have to trash the unison tuning. Hmmm... Interesting, Holmes. >Got any solid evidence or deductive, inductive, reductive, whatever, musings >either way? > >Regards, Ron Nossaman Who, me, solid evidence? Don't I wish! I'll muse for hours, till everyone wants me to stop ...
