Hi Don,
It (they) wasn't (weren't). The low tenors were all significantly sharp
(not flat) - like I wrote. The humidity at the time was just a little
higher than it had been a year ago (but not much). I would have thought it
might just be a weird isolated case, but I've been finding this kind of
thing for the last couple of weeks in all sorts of different places. With
no way of knowing what the pianos have been through by way of humidity
changes since I last tuned them a year ago, I can't begin to account for
what I'm seeing. I'm not all that sure I could make sense of it if I did
know the day to day history, but I found what I found even if I can't
account for it. That's my story and I'm sticking to it.
