<DIV><BR></DIV>I'll try pitchlocks. I've never used them in this section of a
piano, though - I presume they'd have to go at the back end of the speaking

<DIV>I've already tried the voicing route, and it helped, but the noise is

<DIV><FONT face=Arial size=2>Pitch locks are an interesting suggestion.
They're cheap and won't hurt anything. And it would be a great discovery if
they stop the longitudinal wave.</FONT></DIV>

<DIV><FONT face=Arial size=2>For longitudinal mode sounds, Jim Ellis'
book does not recommend changing the string gauge. He suggests (without a
lot of enthusiasm) softening the hammer enough to reduce the energy in the
higher partials. He also says you can try moving the strike point in some
circumstances. You could try sliding the action out a bit to see if it makes
a difference, and if you are very lucky, rehang the hammers.</FONT></DIV>

<DIV>Do you have any Pitch-locks to try out?</DIV>

href="mailto:akwright@btopenworld.com">akwright@btopenworld.com</A>><SPAN
class=Apple-converted-space> </SPAN><BR>Has anyone working on
Hamburg Steinway B's (or similar instruments) encountered shimmery high
partial noises (quite noticeable) at the level of 4 octaves up (perhaps
at the major seventh pitch or thereabouts), in the area around E3 in the
plain wire tenors? Perhaps half dozen notes stand out like this. I
notice that the sound greatly diminishes when I detune the notes by a
semitone or so...is this the longitudinal mode behaviour I've read about
in previous threads?
<DIV><BR></DIV>
<DIV>And if so, are there specific recommendations for changing wire
gauge there in order to eliminate or improve this problem? I'd love to
try something like that - this is a piano belonging to a customer who's
really bothered by the sound. Personally, if it were my piano I think
I'd ignore it and probably not be bothered by it much in a musical
context; but you all know how these things go - that sort of suggestion
often doesn't fly with the concerned customer.</DIV>
<DIV><BR></DIV>
<DIV>Any opinions/suggestions will be most welcome. I've been able to
otherwise even out the voicing nicely, with some lacquer in the bass and
judicious shaping and needling elsewhere, which leads me to be
optimistic that if I can minimize this "feature" the customer may
ultimately be quite happy with the piano again. The piano is in the
shop, which means I can go at it methodically and even
experimentally.</DIV>
<DIV><BR></DIV>
<DIV>Sincerely,<BR><BR>
