Hi Susan, 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. Everyone has= automatically assumed this to be the case, but is it? I have observed a= dramatic drop in pitch with a hard blow as the string renders through the= stagger, 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. 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 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. If the string has moved= THROUGH the bridge pins, wouldn't downbearing pull it down too? 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?=20 Regards, Ron Nossaman At 05:24 PM 4/16/97 -0700, you wrote: >One small question keeps occurring to me as I read this thread: > >If, as seems possible, hard blows are enough to cause the strings to ride= up >on the bridge pins, and stay there, is it a good idea to reseat them?=20 > >Would it be better to consider who is going to play the piano next?
