<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2>Pretty common problem. Here in Virginia, if you
look up the definition of "false beats", they usually have a picture of a
Wurlitzer spinet alongside it. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>There are lots of reasons known and suspected of
causing false beats in any piano. But, I have my own theory about them in lower
end pianos. Quite often, I am called to tune a spinet that has not been
maintained at all for many years. "The grandkids are taking lessons and they are
over here every afternoon. So, I thought I'd get it tuned even though its only
been 20 years since little Suzie our daughter was taking piano
lessons!!"</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>By the time I see this piano, it is often 65 to 100
cents low in pitch. Often I do not notice false beats (especially in the 5th and
6th octaves) at that time. But, after pulling pitch up to at least near A-440,
false beats are all over the place. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I suspect that the bends in the wire at the bridge
pins are being pulled into the speaking length of the string. And, I further
believe that this bend permits or encourages or causes the wire to vibrate
irregularly; i.e., yielding false beats. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Its not just Wurlitzer's, of course. But, since we
see so many of them, it would be natural to make the association. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Just a hunch. </FONT></DIV>

<P><STRONG>Can someone tell me why Wurlitzer's ,mostly the spinets are nothing
but one BIG false beat. A whole lot of my customers here in central Texas have
them.</STRONG></P>
