This works well to mute off large sections to find a damper = leaking a sympathetic vibration and is also good for determining when the owner or = artist is offended by the sounds from the front or rear duplex = sections.   Another thing I haven’t seen = listed in this discussion or in the recent discussion in the journal is using = small pieces of bushing cloth on individual duplex portions per note rather = than muting off the entire section. Just cut a small square or rectangle = and place it over the center string and under the two outer strings. Then the = “duplex mute” can be slid close to or farther from the capo (closer mutes = more) thereby adjusting just how much high end is lost from the duplex rather = than killing it. The notes an be blended very easily and solve many = voicing problems. If a note is particularly strong, two pieces can be applied. I find = this particularly useful on the front duplex in the lower capo = section.   Advantages: quick, economical, controllable and easily reversible.   Back to the original discussion, I = had to use one of my “trouble shooting strips” on a = customer’s Knabe. It now resides on the speaking length of the top treble section muting = some of the over ring which she finds more objectionable than the loss of tone = in the top two octaves. It’s her piano… I hope this helps,   <div> Allan L. = Gilreath, RPT Allan Gilreath & Associates, = Inc. 515 Oothcalooga = St., Suite I Calhoun, GA 30701 <a = href="mailto:agilreath@mindspring.com">agilreath@mindspring.com</a></sp= an>   Berry College – Rome, = GA </div>   -----Original = Message----- From: = caut-bounces@ptg.org [mailto:caut-bounces@ptg.org] On = Behalf Of Jim Busby Sent: Monday, March 15, 2004 2:34 = PM To: College and = University Technicians Subject: RE: Treble = ringing problem   Hi = all,  </fo= nt> Dean Garten uses = 2 or 3 small narrow bean bags to mute off sections/areas. It helps you find = problems and works well to temporarily mute the upper strings while tuning. Before = threading braid this is a quick way to diagnose and it really does aid in tuning = to “shut off” the upper section.  </fo= nt> Jim = Busby -----Original = Message----- From: = caut-bounces@ptg.org [mailto:caut-bounces@ptg.org] On Behalf Of Susan = Kline Sent: Saturday, March 13, 2004 9:43 = AM To: College and = University Technicians Subject: RE: Treble = ringing problem   At 08:21 AM 3/13/2004 -0700, = you wrote: I think I'll start with stringing braid in the duplex in the mid and upper range = (not the top section).  Don't = forget to investigate the backlength of the long tenor strings. If you pluck them and hear the same sounds as the after-ring they may = be contributing to it. If you wrap a whole bunch of the waste lengths on the piano you can really gut the character of the sound. There's a happy medium there someplace. Susan </div> </body> </html>
