<DIV><FONT size=2 face=Arial>Ed,</FONT></DIV>
<DIV><FONT size=2 face=Arial> First off we don't know if this a grand or
vertical or what size.</FONT></DIV>
<DIV><FONT size=2 face=Arial>Does the ring a sound like an open string
vibrating sympathetically or an "escaping" higher partial ?</FONT></DIV>
<DIV><FONT size=2 face=Arial>The first thing that comes to mind is that the
pedal is holding a few dampers off the strings. Push the string away from the
damper to confirm that every damper head is following the string.
Make it ring and touch each unison and that might isolate the problem.Make it
ring then place both hands over the entire bass string section. If it's a
vertical make it ring then block off several unisons at the start of the tenor
section. You've perhaps seen the old Steinway uprights and some Yamaha studio
pianos with aux. damper(s) in that section . Also check the back
scale string segments .</FONT></DIV>
<DIV><FONT size=2 face=Arial>Just guessing here cause' you got the ears on the
scene.</FONT></DIV>

<DIV>I have a problem I haven't been able to solve. The piano is a Mason
& Hamlin, probably 15 years old, and there is a very strong after ring
especially in the middle range of the piano, from C3-C5. The dampers are
good, and have plenty of pressure on the strings. I have tried to damp
off all the bass strings and the ring is unaffected. Even when I have
damped off virtually the entire piano, it still rings. The piano is in
good condition, the pedals are adjusted correctly. Everything seems to
be working fine, but I can't make any headway on the ring. Any
thoughts?????</DIV>
