Don, List, This has been a mild winter here in Shawnee, Oklahoma, USA, nothing to take note of, yet I have had many pianos go extremely flat where that had stayed relatively around A440 in one or two past tunings. Just today, a small quality grand at the bass / tenor break was over -40 cents at the first plain music wire. Never done that before and has been in the same protected institutional environment for 20 + years. No DC unit. I've long since given up trying to figure out why pianos sometimes go awry without any apparent obvious reasons. I just bring 'em back where they belong.
