strict temperature effects

[Alexander Galembo]

I have participated (1970-ies) in the research of  "temperature vs. pitch"
in vertical pianos, but this research was related to metallic frames
rather than to soundboards (we compared cast-iron and some aluminum-based
alloy as  materials for the frame). Metallic frames changed sizes and
strings' pitches drastically with the temperature changes. I don't have the
data with me, they are in Russia, but if interesting, I will have an access
to the report this October.
