This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment I have found that after a couple of regular tunings I often find that = one time the piano will be 5-10c sharp and the next , in 6 months, 5-10c = flat. I seem to find if I leave it sharp it stays sharp and if I = flatten it to 0 it goes flat. Hard to outguess.

I thouroughly cleaned the strings, tuned the piano a couple = of times, and went back a week ago, and voila--no more corrosion! Not = only that, the bloody thing was so close to being in tune I almost felt = badly taking the money--well, not really...=20 #2. I've been tuning a Steinway M that has new strings, hammers, = pins, block, wips, but I'm not sure about the board. She's a very good = customer, gets her piano tuned every 6 months like clockwork. I first = tuned the piano 2 years ago, and today was my fourth trip out. First = time, it was 10-15 cents flat. Second time, it was 10 cents or so = sharp, third time, 10 cents flat; today 5-10 cents sharp. I do know how = to stabilize a piano, so this was a mystery to me. At least until I = heard the air conditioner go on. =20 It's been hot in these parts lately, and pianos are going flat in = droves(the houses in this part of CA are built for earthquakes, not = inclement weather), but in the case of this piano, it's in a very large = luxury home, with all the amenities. Unfortunately, the piano is = directly under a duct that dumps cold, moist air directly on it. I'm = convinced that is what's going on here. In the winter, the heat comes = out of the same duct, but to slightly less effect, since the heat rises. = The duct is now permanently closed. More details next time.=20 Any comments or thoughts on this one? Just thought it was kind of = interesting. =20 Dave Stahl=20 ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
