Put a digital humidity-and-temperature gauge on top of the piano, or in the keybed area, and take a reading. Then place the humidity gauge on top of a backpost, and take another reading. When I did this on a Steinway L near the coast, my readings were: 70º F, 60% RH on top of the piano; 77º F, 51% RH on top of the backpost. It's true that vapors try to disperse evenly throughout a container, _but they take time to do so_, just as heat does. We should be glad of this: all sorts of things which we take for granted would be seriously awry if this were not so. For instance, wearing a toque and muffler wouldn't help our Canadian friends to stay warm. Sincerely, Susan Susan Kline P.O.
