Pitch Floating

[Don]

Hi Avery,

I have kept records for many years of humidity change v.s pitch. The first
visit to a piano for me is *always* to strive for A440. After that, if
humidity is not controlled I usually unless other wise required by the
client do the following:

         If the humidity is rising the low tenor will be sharp. The
stabiliest part of *most* pianos are the first few notes below the bass
break. When humidity is higher, and the pitch at A4 is sharp I will choose
an average of 4 four notes in this area to float pitch. This means I will
have to lower the low tenor, and possible raise the treble area. 

        If humidity has gone the is lower and A4 is flat then I will raise
the pitch to A440. A4 thus becomes a *go* or *nogo* as far as pitch
correction is concerned.
