Michael, Roger: At the University of Redlands, if the pianos are at A-440 in May, they could be at A443 or A444 in late August. If I tune them at A440 in August/September, they will drop to A437/8 when we have our first dry weather system, and keep dropping over the winter. Since the contract severely limits the frequency of tuning rounds, I target a two cycle range, A440-442, and except for the performing instruments I only drop the pianos to A442. I never know when the first dry weather system is going to strike - it could happen anytime between September and January. Several times I have completed the tuning rounds and immediately the humidity dropped 40% or more, destroying my work. If I only drop pitch to A442, the pianos will only drop to A439/440 after the weather shift - they might be ugly, but not too flat. In a contract tech situation where there are strong weather influences on pitch, I think a two cycle range gives the most pitch control. I would rather be able to tune more often and keep the pitch within Roger's one cycle range of A440/1.

I can't believe that nobody chewed on it to death before it went into digest form. I guess your point makes too much sense to be debatable. -Mike jolly roger wrote: > > After I wrote, > > "always tune to A440". > > > > Hi Mike, > Above is the only point that I > disgree on.
