humidity effect

[Carol Beigel]

Where you the one who tuned it the last four times?  If not, maybe the tuner 
muted the strings, tuned the middle string, the proceeded to tune the 
tunisons 1 to 2, then 3 to 1 and 2, and wasn't very good at it!

If you tuned the piano last time, try tuning it one single string at a time 
starting with A0 and working your way up to C8, one string at a time.
