Susan, 

Did this sound happen when you jiggled the piano somehow?  If not, did something you did trigger it or was it some random noise? 

Chris 

Sounds like you're on the right track. I wondered if somebody would nail it 
right away. The second occurrence happened as I bumped the right cheek of the piano 
while walking past it, the first as I was pulling out the action.

I put in a long service day on a neglected and much-played 
Mason & Hamlin BB, about ten years old. When I first started 
pulling the action out, I heard a soft repeated Eb7, sort of 
like a very loose bobbling hammer, but not quite. It got 
softer and faster till the sound disappeared, like when a 
ping pong ball is bouncing, and then coming to rest. 

I said, "oops", and wondered if some action trouble had 
a hammer doing a dance in the high treble -- but the 
hammer was down, just like the others. "Go figure", 
I said to myself, and carried on. 

A couple of quiet hours later, with the keys on a little 
folding cart six feet from the piano, and the action reversed 
(hammers out) on the bare keybed to get teflon on the 
knuckles -- there was the same sound again. Eb7. Nothing was 
near the Eb7 string. 

I never have heard that sound from a piano before, let alone with 
no action and keys involved. 

What was it? 

(P.S. I figured it out ...)
