This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment December of '99 I tuned a Baldwin Studio Upright in a small rural church = in extreme northwest Tennessee--the heat had been on in the sanctuary = over night, was a bit cool, yet comfortable, I would judge around 70 or = 72 degrees. Humidity in this part of the country averages around 50-60% = Often around 90%-seldom less than around 30% (we are in the Mississippi = River Valley). The piano has been in the church for around 20 years. = Generally in good shape. Tuned it before, no problem with stability. The lady who contacted me to tune the piano called the latter part of = January and said her son, who is the pianist there, sounded like it had = gone out of tune real bad. I made an appointment to go by the church = and meet her son there. When I walked in the sanctuary, he was playing. = The piano sounded very well in tune--and I began to wonder what was = going on. I spoke to him and he turned around and exclaimed, "the piano = sounds great!" It was the same temperature as when I tuned it. I asked = him if this was the temperature in the sanctuary on Sunday mornings. He = exclaimed, "We try to keep it this temperature, when the old folks come = in they crank it up to where it is burning up!" =20 At my own church I tuned the concert grand in the Worship Center when it = was cool outside, and although the heat was on, it was barely on--around = 72 degrees in WC. Two weeks later we had a cold snap and piano did not = sound as good as it had. Temperature was 72 degrees in the WC, yet the = heat was on. A couple of weeks later we had a warming trend, and piano = was back in tune. During the week, the heat is generally reduced to in = the 50-60 degree range. I believe that the humidity, rather than temperature, has more effect on = a piano stability. Around here where we have fairly high humidity, it = manifests itself pretty dramatically. At the same time temperature (as = well as heat, AC, type of heat) has an effect on the amount of humidity = in a room. Joy!
