<HTML><HEAD></HEAD> <BODY> Does the buzzing stop if you lift the= string behind the agraffe?  I saw a piano once where the= under string felt that was supposed to go between the tuning= pins and the agraffe had been left out, so there was no upward= bearing on the agraffe.  If the string has no pressure on= the agraffe it will certainly buzz.  dave __________________________________________ David M.

The piano has signs of being worked on.  Beside pieces of= felt stuck here and there trying to get rid of the= zinging,  there are Pin-Tite stains on the plate and rock= hard, overly lacquered hammers.  On other pianos I've had= good luck tugging upwards on the string, or cleaning out the= hole in the agraffe.  But that hasn't helped in this= case.  If I push down firmly on the string on the tuning= pin side of the agraffe it stops.  There is felt there so= it isn't a vibrating string.  In my research I found a= Journal article that mentions that maybe the agraffe= itself is loose. I wanted to run this by you all before I began testing this= theory, or perhaps someone knows exactly what the problem= actually is.  (And because I have the piano faculty looking= over my shoulder I  want to be right the first time!) Thanks for any insights. Bob Callaghan </BODY></HTML>
