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!

Poulson Registered Piano Technician Piano Technicians Guild ----- Original Message ----- From: Jason Kanter To: Pianotech Sent: Tuesday, January 16, 2007 8:55 AM Subject: mystery buzz Group - 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: I have a Baldwin grand that has had a buzzing key since I bought it about a year ago... It's the B right below middle C. Been there since new. I'ts not a buzzing exactly, but an "off-color" side tone. The other tuner has worked on it 4 or 5 times, and replaced the string, with no help. Of interest is the fact that I can also hear it on adjacent keys (but to a MUCH lesser extent, almost inaudible). I can't find anything loose that might be vibrating. It's such a commonly used key that it's quite annoying. I notice it even when playing chords. What do you folks suspect, given this description? What else should I ask to get a better premonition?
