<DIV>Hi David,</DIV>
<DIV>All you can do is try to get them to have the piano, up to =
operating
temperature, before you tune.</DIV>
<DIV>I do not believe there is a way to predetermine the amount of =
drift, that
will happen.</DIV>
<DIV>It will happen, especially if the piano is kept in a controlled =
environment
room.</DIV>
<DIV>Waiting for other answers, that might actually solve this =
problem.</DIV>
<DIV>Regards,</DIV>

<DIV><FONT size=2>Is there any way to effectively deal with stage =
lights on
the piano in terms of tuning stability. I recently tuned an =
S&S D
prior to rehearsal in a new venue. The piano was moved on stage =
where it

rehearsal I went to check the tuning and noticed that the pitch had =
dropped by
about 2-3 cents. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I used a Verituner for the first tuning and am =
confident
about the initial pitch setting. I have tuned many stage =
concerts but
not had this happen before. I am assuming it was the lights as I =

feel that they were quite warm.</FONT></DIV>

<DIV><FONT size=2>Is there any reasonable way to avoid or prevent
