Subject: Unpleasant overtone in plain wire


I am working on a 1928 Steinway M that has loud unpleasant overtones in=
 notes E3 to B3. The overtone sounds like an out of tune cymbal or bell=
 about a seventh above the fundamental.  It can first be heard immediat=
ely after initial impact, and has a long decay.  It is not a sympatheti=
c vibration from elsewhere in the piano.  It occurs whether the string =
is struck with the hammer or plucked.  The strings have been replaced, =
leveled, and terminations checked.  Nose bolts are tight. Hammers are n=
ew Steinways.  Hammer voicing reduced the overtone on some notes, but n=
ot on others.  The piano has very little downbearing in the tenor, but =
pressing upward under the bridge in this area does not affect the probl=
em.  Help!
