[pianotech] How come?

Thanks to all who have replied. Unfortunately, even though some also have noticed it, and one person has even had the opposite effect. I didn't read a reason why this is happening. So I guess it's just one of those things that happen, and I'll just have to accept it.

Subject: [pianotech] How come?


I have quite a few customers that I tune once a year, like clockwork. The pianos are very stable, often off by less than one or two cents, all up and down the keyboard, xxcept for the top four or five notes. Invariably, these notes are low as much as 6 cents. When I first came here, I noticed that most pianos were a little flat in the top octave, and assumed the previous tuner just didn't get it right. But now I'm having the same syndrome. 
 
Recognizing that the middle of the soundboard fluctuates the most, and presumably the edges of the soundboard don't fluctuate at all, how come the last 5 or 6 notes in the high treble are going flat?
