<DIV><FONT face=Arial size=2>Jason: Since the buzz is activated by other notes
being played, it is not likely to be a string problem. My first guess would be
either a loose case part or screw, something on the soundboard, or a soundboard
crack rib separation, although this is unlikely if this is a one year old piano.
Loose case parts can be a real bear to track down. Lock mechanisms, hinge pins,
or just about any small screw in the case or action can cause such a buzzing.
Usually I will have someone play the offending note and go around listening to
all sections of the piano. Some technicians use a stethoscope as well. You can
eat up a lot of time trying to find these buzzes. Usually the offending part is
not visibly vibrating, and a half turn with a screwdriver tightens a screw down
and it is gone. Good luck! And charge for your travel time.</FONT></DIV>

<P>Group -<BR>I have been asked to travel a couple of hours to fix a mystery
noise. To save time I asked the owner for as complete a description as
possible. Here's the response:</P>
<BLOCKQUOTE class=gmail_quote

<P>I have a Baldwin grand that has had a buzzing key since I<BR>bought it
about a year ago...<BR>It's the B right below middle C. Been there since
new. I'ts not a<BR>buzzing exactly, but an "off-color" side
tone. The other tuner has <BR>worked on it 4 or 5 times, and replaced
the string, with no help. Of<BR>interest is the fact that I can also hear it
on adjacent keys (but to<BR>a MUCH lesser extent, almost inaudible). I
can't find anything loose <BR>that might be vibrating. It's such a
commonly used key that it's<BR>quite annoying. I notice it even when playing
chords.</P></BLOCKQUOTE>
<P>What do you folks suspect, given this description? What else should I ask
to get a better premonition?</P>
<P> </P>
<P>Thanks in advance</P>
