This piano always has done this but tonight I got fed up = with it. The stringing of these pianos is to Yamaha's "duplex" pattern. I think = it is Yamaha's answer to Steinway's "aliquot" movable bridge - next = to the hitch-pins. I found that by dampening the mid-break aliquot (duplex) = where the listing cloth (stringing braid) ends got rid of this spurious noise. In = Steinway I believe it's possible to move these multi-unit bridges on the plate so = the aliquot resembles a harmonic.(vide Reblitz p.57. photo Illus. = 4-25) In the Yamaha the same seems to apply but it is so wildly off pitch I = doubt it. </FONT></DIV> <DIV><FONT face=Arial size=2>Regards</FONT></DIV> <DIV><FONT face=Arial size=2>Michael G = (UK)</FONT></DIV></BODY></HTML>
