[CAUT] Piano Storage Room

[Andrew Anderson]

The piano is outside and tuned that way.  The climate is separate  
within the piano.  There is an undercover but, no, there is no  
stringcover.

Maintaining a piano in a climate controlled box may be good to protect  
the piano but guarantees instability when it is put out on a stage  
with inadequate climate-control.
