<DIV><FONT face=Arial size=2>Sara,</FONT></DIV>
<DIV><FONT face=Arial size=2>Is there a ceiling fan, or perhaps a window fan
running anywhere in the same house as the piano?? I used to go nearly nuts
trying to deal with "false beats" that were not there but were being caused by a
fan, sometimes in another room!! It is getting into the really warm part of the
year and would make sense to be running into running fans. </FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> False Beats in the Temperament
Section</DIV>
<DIV><BR></DIV>
<DIV>
<DIV>I'm looking for suggestions, guidance, admonitions, whatever, please.
</DIV>
<DIV> </DIV>
<DIV>My piano for practicing tuning (and playing) is a 3 year old Pearl River
upright (UP 118E, 47" ). It has developed murderous false beats in the
temperament section making aural tuning practice impossible. The only thing I
can really practice aurally at the moment is minimizing false beats in
the unisons. There aren't enough intervals clean to let me
get anywhere. All 3 strings on A4 are funky. On many strings I
just can't read a pitch with a resolution greater than 1 cent because of the
oscillation. Some have a larger oscillation. I noticed it is much worse when
the humidity increases. This piano does have a DC system that is always
plugged in and working. </DIV>
<DIV> </DIV>
<DIV>Logically, I guess the first thing to do would be to seat the strings.
This will be somewhat difficult because of the location bridge pins for these
strings relative to the keybed. I have ordered Joe Goss' string seating tool
to help with that. </DIV>
<DIV> </DIV>
<DIV>If I can't get it resolved, I'll certainly find the money in the budget
to get someone from my chapter to come in and work on it. </DIV>
<DIV> </DIV>
<DIV>Thank you!</DIV>
