Bill With as cold as it has been, the heat is on constantly, and even more so during the night. I have a feeling the buzz is caused by something that contracts or expands when the heat comes on, like the heating vents.

I have a customer who's 1+ year old Baby Grand has a buzz.. particularly at 3-4 keys around G5. But when I was sent out on a warranty call the buzz was gone. I went thru a Pitch Raise and Tuning (since it needed it), and "nothing". It sounded lovely. A couple of weeks later the buzz is back, supposedly along w/ a pedal noise. Confirming the next day's appointment last night the noise was there. I called this morning before I left, and the noise is gone again (so I didn't go). The customer is over an hour's drive into rural America, so they agreed to wait til the noise returns. They have an upcoming "recording", when of course they don't want to hear the buzz, so they are nervous. Any ideas??
