Well... yes. But in my experience the kind of movement in the piano you describe usually takes more then a couple days of somewhat lower then usual RH. Could be the piano just <<gave in>> to the change. Still... 24 cents of movement on a stable instrument after two days of moderate (?) drop in RH ??.... stranger things have happened but..... I have to hang my hat on the doubtfull krage. Cheers RicB ------------ Previous tunings (every six months) never varied more than 5-7 cents. Houses here are central heat/air, and normally really locked down. Most never open windows. Could two days in relatively low humidity, with no heat or air, make that kind of difference? les
