In the p[ast 3 years I have restrung two D's that have a tuning stability problem. (original block). I've restrung other D's, but I don't see those pianos any more. One of them is in our Chorus room. I tune that piano once a week, and everytime there are at least a dozen or so strings that are off more than they should be. I haven't kept track of exactly which strings are off, but I don't think they are always the same ones. I've tappend, and set and pounded, but some strings still go out. The other D is in a large church, which I restrung it last year. Again, there are individual strings that go out. At first I attributed the problem with the way it is being played, and that there is an air vent up in the ceiling that blows directly on the piano. The problem has gotten so bad that they took that piano out of the sanctuary and are now using a 6' Yamaha. (the sanctuary seats about 3000.) So my question to those of you who have restrung more than 2 D's is, is there anything you do different stringing a D than you do when string a smaller grand? I have strung litterally hundreds of pianos, but I've never had a problem like this. Any suggestions will be appreciated.
