This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment I need some input about a piano that has a serious damping (actually a = non-damping) problem. Tones continue to ring after the key is released. = It is particularly bad on F#4 which rings at its own pitch, G#4 to a = lesser extent, and C#3, D3, and D#3 which rings at the double octave + = 5th. The piano is a Baldwin Acrosonic #386458. The owner is a piano = teacher which makes the problem a bit more acute (It's driving her out = of her mind). So far I have adjusted the pedals to be sure that they are damping well = and they seem to be. I tried muting the non-speaking parts of all = strings, and blocked off all the bass strings in their speaking lengths, = as well as the treble strings above the dampers. F#3 still singing like = a canary. I even blocked the F#3 string itself, and it goes "Bonk" when = the hammer strikes but continues singing the tone the same as before. I = moved the piano out from the wall and checked to make sure there was = nothing contacting the sound board. I tapped the strings to the bridge = to be sure that there wasn't some risidual vibration being made there. = There is a bit of a false beat in the left string of F#3, but that = shouldn't cause the excess ringing. G4 not ringing, F#4 and G#4 are. =20 There are a lot of knick-knacks in the room, and I wonder about = suspecting some vibration in that area.=20 If anyone has a suggestion as to what I might try in order to eliminate = this annoying problem I would be grateful for your input.
