<DIV><FONT face="MS Sans Serif">Try very slightly mistuning the E6 unison. Not enough to make it noticeably out-of-tune, but enough to change the timing of the coupled effect of the strings and make it slower to react to partials in other notes.</FONT></DIV>
<DIV><FONT face="MS Sans Serif">(Hey, it's a long shot, but easy to try.)</FONT></DIV>
<DIV><FONT face="MS Sans Serif">Also, I'm wondering did you perhaps retune, changing the stretch in the top?</FONT> </DIV>

<BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: blue 2px solid"><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>Have you investigated the long waste lengths on the bridge end of the tenor section? I've had a few pianos where one (or another) note around the sixth octave would ring on too long and too loud. I tried plucking all the different waste lengths (especially the ones behind the bridges) that I could. Sometimes it seems like a bunch of them are reinforcing (mainly) just one note. </FONT></BLOCKQUOTE>
<DIV>I thought it might be a bunch of sources, and I used 3/4" stringing braid to mute any non speaking string lengths. I didn't notice an improvement after doing that. I found that if I played a loud C major block chord, the E6 would ring, and if I touched the speaking length of that note, it stopped immediately. And if I muted E6, I didn't get the after ring. So I am pretty sure the culprit is E6. </DIV>
<DIV> </DIV>
<DIV>I did find that many of the waste ends rang at that same pitch, so I thought I'd be cutting the volume of the after ring by muting everything. But the main piano teacher called me later, saying she hadn't noticed any change. (I was surprised that she didn't notice a change in tone of the piano since I muted any non speaking sections.)</DIV>
