humidity effect

[Carol Beigel]

I agree that humidity affects piano tuning in many mysterious ways, but I 
really don't think humidity has anything to do with your present 
observations on this piano.  Since all the tunings were significant pitch 
corrections  I would think bridge roll could be a factor.  I,m still 
serious, though, about tuning the piano starting at string #1 and go one at 
a time through #235 (or so!)
