<html> Hi Tom,<br>             We see a few of these problem pianos from cottage country, combined with the high humidity from off the lakes in summer.  Pitch tends to be very unstable at best. Loose pinning and cracks of all types, is common place.  To contradict this, some pianos survive remarkably well.<br> The newer the piano, the more erratic the swings seem to be.<br> You can predict nothing,  all you can advise is this not a recommended way to care for a piano, so owner beware, they are taking a big gamble.<br> Roger<br> <br> <br> <br> At 06:31 PM 09/09/00 -0400, you wrote: <br> <font face="arial" size=2><blockquote type=cite cite>A client asked why a piano shouldnt be in a very cold space, i.e. Winter in northern N.E. in an unheated home. Reaction to extreme humidity swings is well known, but what actually happens to a piano @10 degrees  F. for example when brought to 70 degrees within a few hours.
