[pianotech] Humidity

I also don't think that 4% is too much of a problem. I do think it's a  
crime what they do to us.
86 degrees! I'm counting the days to October.

So, how  important is it to have a sanctuary at the temperature it's used 
at when you  tune the piano?  How fast does the wood take on or let go of the 
 humidity?  If it was 60% when I tuned it (and 86 degrees Fahrenheit) and  
it's only 56% when the A/C is on, how much will the piano change in  pitch?  
I can ask churches to cool down or heat up the room to the  appropriate 
level, but if they …forget... do I have to reschedule?  I'd  love to hear your 
opinions.

Thanking you in advance,
