Temperature Change affecting pitch

[Don]

Hi,

I have been observing this for years...and it seems not quite random...the
treble side wires on unisons will all go the same way and the bass side
wires go the same way...depending on whether humidity is going *up* or
*down* so a unison would be UUU then after change might be FUS or SUF, with
the middle wire also going up and down in pitch depending on direction of
change.
