I remember the late Ernie Juhn, during a class, related a story about 
neighbors in an apartment building with identical model Yamaha 
uprights, one of which had major tuning stability problems, while the 
other was stable. Eventually Ernie had them temporarily swap, and the 
instability transferred to the "new" piano. Eventually I believe he 
discovered that family had a penchant for "warming up" the bathroom's 
shower, by turning it on with the door open for a half hour every 
morning. Once the shower routine was adjusted the piano returned to 
stability.
