I know we improve as we go along in this field, but I was worried that my skill was slipping or that something was wrong.  I almost felt panic. So to repeat, the humidity outside can still have an affect on a piano inside even if the temp inside is pretty even?  How does the piano feel the change in humidity outside then if the room in this case a fellowship doesn't have windows?  We've had our share of up and downs with weather here onthe east coast, rain humidity, a little dryer/cooler earlier this month and then warmer and more humid again.  In fact when I return next month, I'm going to check it again becase we're supposed to get cool again this weekend and maybe warm up again.  Thanks again guys. I hope youu can ease my mind over this this.
