I have had them go out of tune right under my hand while tuning. A winter dry board can absorb mousier when the outside doors are opened for a load in. It takes 30 minutes and more for it to come back down to to near where it was. This is a royal pain on stage. A hot dry draft can effect a piano immediately in the opposite direction. Newton
