Temperature Change affecting pitch

[Larry J. Messerly]

I do take RH readings each visit.  The indoor air in our dry summer is
always higher than the outside RH.  I presume because the AH remains the
same, cool air has a higher RH.

ps we do have many evaporative units (swamp coolers) in Arizona.  They
really pump up the moisture where I can measure 20% RH outside the house
and 80% inside.  I've seen strings go rusty (in Arizona) in less than a
year because the client would not move the grand piano, close the lid, or
close off the air vent.
