[pianotech] piano going out of tune

[Tom Gorley]

Marshall, consider buying a hygrometer to measure the humidity when you tune the piano.  You don't have to guess the humidity outside-versus-
inside.  The one sold by Dampp- Chaser costs about $45 and will also measure the high and the low. 

 I always carry one in my tool box and when I suspect a changing humidity issue in the room, I leave it in the piano.  The next time I check the piano I can read what the humidity high and low during that period of time.

So I billed them for a "touch up" tuning.  I felt I had to do this because I do use public transit often when I tune there sometimes with the cab, tip and train even with my discount card on the train the total one way can be over 10 bucks.  I hope I'm not wrong in trying to make a profit.

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.
