---------------------- multipart/alternative attachment Stephen The questions are not as much stupid as they are irrelevant. Neither are true cases. But the conepts are somthing we can use. In the first scenario, a piano goes out of tune more because of temperature and humidity changes, than it does playing. So in the situation you described, the piano probably wouldn't fluctuate more than a few cents in the period of a week. Certainly not more than 10 cents, if that much. In the second scenario, the piano would fluctuate back and forth. It wouldn't necessarily drop in pitch. During the shower, or right afterwards, the piano would go sharp, especially in the middle, where the soundboard would gain a lot of moisture. Then when you turned on the heat lamp, and removed the humidity from the room, the soundboard would drop again. But because it takes several days for the humidity to enter the soundboard, and a few days for it to leave, the overall effect would be a raise in pitch, rather than a drop in pitch.
