[CAUT] Piano Storage Room

[Ed Sutton]

What are we comparing here?
48 hours out of a climate controlled room with a few minutes of an unplugged 
DC system?
I don't know what to make of it.
A closed piano lid, or a string cover, make a micro-climate which is lost 
when the cover is opened and the string cover removed. That can make a 
dramatic temperature change with resultant pitch change.
What would be the point of a string cover if it is removed for the 
performance? It could make for a big tuning problem.
