Piano tuning - this is getting a bit off subject, but since it pertains to dimensional stability of wood, I thought I would clarify briefly since I am an (ex) classical musician who played for 12+ years in an orchestra:

1. pianos are under a great deal of strain because of the strings' tensions 2. pianos are customarily tuned for home use twice a year based on seasonal changes 3. concert grands are customarily retuned for the soloist's ear, that is, a Horowitz tuning would be different from a Van Cliburn tuning. 4. pianos do not visibly warp.
