I wasn't wanting to assert that this was an extraordinarily precise experiment (determining that 10F drop in temp = 2 cents rise in pitch), just that the observations I made were suggestive. I was more interested myself in the fact that the pitch changed in this case pretty much as a whole, without distortion across the scale. I would have expected more variance, say between plain and wound strings, or between long and short ones. What we need in order to learn something really solid, of course, is actual controlled experiments. But that takes more time and logistics than any of us have, I guess. Doing a truly controlled temperature change where other things like RH are kept constant isn't a simple matter. If that ability were available, it wouldn't take much work to do the observations. Maybe someone will be inspired to recruit a science or engineering class to investigate. Regards, Fred Sturm University of New Mexico fssturm at unm.edu
