Thanks Fred, that's why I asked. Here, we get up in the 70s%RH 
inside in Summer, and usually not much below 25% in Winter, 
though it's been dryer this year. Winter brings the complaints 
about tonal problems anywhere and everywhere from octave 5 up, 
and Summer brings the magic and often dramatic sweetening of 
sound, disappearance of killer octave attack "splatter", 
increased sustain, and spontaneous healing of false beating 
trebles. With drier wet cycles, there wouldn't be the contrast 
that makes the yearly dry season complaints so obvious. I know 
we all grade on the curve from lack of having experience at 
EVERYTHING possible. But then plenty of my own brain cells 
haven't checked in for some time now either.
