Hello, Clyde --

That has not been my experience, either with my family's pianos (a Haddorff
spinet and a fine 7 foot Baldwin from the 30's) or with stringed instruments
such as my cellos. 

IMHO (always my humble opinion) it's not the dryness that is the killer, but
the cycling back and forth. In fact, I think that given the choice between 
_always_ very dry or _always_ very damp (without the choice of _always_ nicely
in between) the dry will win hands down. I've seen pianos from Montana or 
Idaho arrive in the Central Valley of California, untuned for 20 years. I had
two the same week once, which got my attention. Under a light patina of fine
beige dust, they looked brand new! And they were both 1/4 tone sharp! No doubt
this sharpness was only from the higher (but not _very_ high) humidity in 
California. 

One could do much worse than take a healthy brand new piano and move it 
to a persistently dry climate. If it's dry enough, it's almost like putting
the piano in a time capsule! Remember hearing about the wheat which they
found in the desert Indian ruins? Carbon dating made it over a thousand
years old, and it still sprouted!

Regards,

Susan
