Any strategies on tuning when there is a D-C installed? When I open the piano, the humidity starts to change. After a while this affects notes I've already tuned. In my case, the humidity near the action of my vertical changes from 42% to 36%. After a half hour or so of practicing setting a temperament, my first notes have drifted a bit from where they were. I assume the humidity change is the problem, but I suppose it could be how I set the notes. Do people run into this problem? If so, would you recommend leaving the piano open for a while before tuning? Charles Neuman
