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.=20 Regards Michael G (UK) ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
