Bald Ham Pitch Swing

[John M. Formsma]

Hi Stan,

You asked:

<<<...but none as peculiar as a Baldwin Hamilton (<10 yrs) on which the
entire tenor/treble section fluctuates 25-30 cents each seasonal change.
The bass remains within 5 cents of pitch on this piano.  Is there more to
this phenomenon than the soundboard swells or shrinks?>>>

I have wondered this as well.  But, what else *could* cause this?  Seems
like the fluctuation of the soundboard is the only factor in this equation.
