buzz

[Leslie Bartlett]

Nope, I know nothing except that it is a Steinway D, I think I recall, new
customer, and he says he has a "buzz" .............  I will see what I see
when I see,and maybe hear something too.  I'll have my new technology by
then......

When I worked for the Yamaha store in Portland, I soon became known as the 
buzz finder.  It is one of the harder parts of our job--for anybody.   The 
main thing a person needs to find a buzz is persistence.

I even remember once, about 25 years ago, Murray and I were on a tour of the
US and Canada in our motorhome.  We were in a library in Columbus, OH, when
I suddenly thought I heard a piano being tuned.  I was at a stage in my
learning when I thought I heard pianos being tuned all the time!  But this
time it didn't stop, so I went to find the source.

Sure enough there was a piano being tuned.  I met Ellen Sewell who was
busily tuning the piano for a community concert in the library.  She greeted
me enthusiastically and said, "I have this buzz, maybe you can help find
it!"  Together we searched, and searched and searched.  Eventually we found
out it was in the lock--which she had already checked before I got there.

Then there was the Steinway upright in our shop.  My father, Bob Hofstetter,
RPT, couldn't find it, I couldn't find it, Murray couldn't find it.  The
California  State Convention was put on by our chapter.  Afterward about two
dozen techs came to our place for dinner.  After dinner, I challenged the 
group to find the buzz.    They were climbing all over that piano.  No one 
could find it.

Only one man stood back, so I asked him, "Jim aren't you going to try to
find our buzz for us?"  So he simply said,  "NO, I already know where it
is."  He pulled a thin, steel 6" rule out of his pocket, walked around
behind the piano and showed me where the Steinway upright soundboards
traditionally come unglued from the rim.

So, unless you are Jim Coleman, and the piano is a Steinway upright, you
have to reconcile yourself to the fact that it might just take a long
time---and on the other hand, you might just be lucky and find it right off.

Can you give us any more info about the piano?

Les,
I seem to remember that you may use hearing aids (I think I recall you're
pretty happy with your audiologist). Given that this noise just might be in
a difficult range for you, this might be a great time to employ a younger
assistant for this or a followup diagnostic visit.
Sometimes it is *so* hard to isolate a buzz, and an extra pair of hands is
invaluable. The extra ears could help too!
When you isolate what keys (at what key force) produce the buzz, assign the
assistant the task of repeating that note while you push on the soundboard
in suspect areas, check casters and other case parts to see if they are
causing the buzz etc. Of course the buzz could be from loose screws on the
key upstop rail or hammer rail (probably my first area to focus on) so you
should pull the action and address this first.
Pictures on the walls, stuff behind the piano if it's an upright, are also
likely culprits. Screws, marbles, shards of glass under the plate.
Time to voice super hard (or worn) hammers? Tighten all action (and
case) screws? Twist a bass string? Replace a bass string? The list goes on
and on.
Invite the young Associate who lives nearby, or some other young pair of
hands and ears to join you on your detective mission.
Patrick Draine (who does not have an assistant but realizes sometimes I
should)
