<html> Hi Eric,            Instead of muting the duplex completely, take a dab of white glue  about 1/4" in front of the duplex bar. this will not kill the duplex, just change the pitch, I did this on an A 3 on a older Yamaha CF with nice results.

In looking for more "sparkle" (or something) in the tenor section, I finally noticed the braiding and removed it. Of course a sympathetic ringing immediately appeared which I was able to easily track down to one duplex segment on one note  (G#4, I think). I muted off that string segment and the ringing ceased. The overall improvement was not dramatic and may well have been imaginary, but removing the braiding did seem to bring a bit more "life" to the tone. ~~~~~~~~~~~~~~~~~ Eric Wolfley,= RPT Head Piano= Technician Cincinnati College= Conservatory of Music University of= Cincinnati ~~~<font= face="Copperplate Gothic Light" size=2>~~~~~~~~~~~~~~<font= size=3> <ul> -----Original Message----- From:  Mark Cramer= [SMTP:cramer@BrandonU.CA] Sent:  Friday, May 12,= 2000 10:14 AM To:    CAUT= (E-mail) Subject:       = Overnite relief End of February I aksed for (overnite) advice on how to deal= with sympathetic ringing in the treble section of our recital hall= "D."  With the Egré competition here last week, I finally found time to= thoroughly trouble-shoot the problem.  Which is kind of like saying "while= being chased by a doberman, I finally found time to work on my running= technique!"  :>) The ringing is (was) from the tenor rear duplex section, A3 was= singing along with A5, etc., as I think Newton had suggested.  Braiding the= section off solved this problem, without noticeable effect (to my hearing) to= the overall resonance of the piano.
