It does not take much swelling for a key to stick, for a hammer shank to warp, or for a window to stick shut. It does not take as much swelling as one may think for a pianos pitch or tuning to change either. If it did, tuning and pitch would not change nearly as much as it does.

Yes, I've taken a whole lot of time trying to learn how things actually work, rather than assuming that what I was taught was correct. It used to be common sense that horse hairs in the rain barrel turned into worms. I take the time because I'm interested in learning something real. Ron N
