6 month tunings may work, in some places, but here in Nova Scotia, that would necessitate a 'pitch raise', each time. I recommend to the majority, of my customers, that they tune once a year, when the heat is on. (Gives me the Summer off) Then yes it is within a few cents, because the humidity is roughly the same. Naturally, if it is a serious player, they require more frequent tuning, and I recommend a Dampp-Chaser system. I can't understand, how someone can go back three months later, and the piano is within a few cents. Does this mean that other places, don't have seasonal changes, in humidity, like I do???? Most people understand, the problems with a pitch raise, when I explain to them, that I am increasing the tension, on the bass, and when I get to the treble, it will affect, the bass. I say something like a see-saw. They have no problem, understanding. John M.
