The = last several tunings I have been warning her that numerous tuning pins appear = to barely be holding and sometime soon we will likely have to do something = about that.

We go over options to repair loose pins. She's not ready to restring = (piano needs it), so we decide to go with CA glue on pins. So I check out = piano. Indeed, nine bass notes ranged from 25 to 60 cents flat (every other = note on piano was within a cent or two of target - a few bass notes were a tad = sharp - likely in response to the few notes going flat).<BR>> ><BR>> = > BUT - five of these notes were wound bicords. AND BOTH STRINGS ON ALL FIVE = NOTES WERE EQUALLY FLAT! I'm saying that the notes that were 25 to 60 cents flat = had perfectly tuned unisons. Obviously, one would think that pins letting = loose would be an arbitrary occurrence - one here, one there. It's almost like = someone that knew how to tune a unison but not an octave tried to "fix" the = tuning. I asked her, and she said no one has gone near the piano with a tuning = wrench (maybe I should have asked about vice grips!) since I was last = there.<BR>> ><BR>> > Anyway, anyone have a reasonable explanation how this = could happen? Boy, I don't know what the odds are against a random occurrence = like this, but I'm sure they are not quite as good as winning the = lottery.<BR>> <BR>> _______________________________________________<BR>> = pianotech list info: <A href="https://www.moypiano.com/resources/#archives">http://www.ptg.org= /mailman/listinfo/pianotech</A></DIV></BODY></HTML>
