My directors are seeking a remedy for cold weather and keyboards. We all know what happens: keyboards go sharp and the winds go flat. Diverging pitch directions. My guess is that even blankets on the boards would not make a discernible difference once the keyboards were exposed to the air. But, in the interest of research, and anecdotally so, if you think there is something that can help lessen the pitch difference between keyboards and winds in colder weather, please do let me know.
p.s. It does get cold in Alabama. We had our sectionals last evening and it was in the 30's.
