I have replaced strings that were beating so falsely that I couldn't
tune them, and the brand new wire had the same problem! I have taken the
bridge pins out and renotched and repinned a note on a bridge and put the old wire
back up to tension and the falseness was gone. I assume I didn't pull the
wire back exactly to its original position, so there had to be some deformity in
the speaking lengths. Didn't seem to matter. The note was far cleaner than
before.
I have gotten the same results from everything I have tried with false
beating strings. Seating the strings with a very light tap sometimes makes a
big change, and sometimes nothing. Sometimes a tap on the bridge pin solves
all problems. Sometimes new wire helps.
I have several high notes on a concert piano here that are untuneable.
When I address this over the break, I will not waste time on trying to see
what particular remedy works. The first thing to try is one drop of super thin
CA at the base of the bridge pin. Not because this has any historical weight
behind it, but rather, because for the investment of time, this gives, by far,
the best chance the falseness will stop. If that doesn't help, then I go
ahead and do everything.
I will, instead, check the bearing, remove the wire and renotch. I
will either repin the bridge for that note or treat the wood before driving the
originals back it. I will inspect as well as fondle the capo bar, searching
for anything amiss. I restring it. If it still sounds like before, I check
for nearly sympathetic lengths in the backscale. Sometimes there is a need to
"detune" an aliquot's note, which I do with a slight kink in the duplex length.
I tune it around some, seeing what extraneous woes can be cancelled by
controlled mis-tuning.
Then I move on, no need being a damn fool about it. False beats are a
fact of a tuners life. They take more of a toll on the beginning tuner
seeking perfection than the older one who knows when to quit.
Hope all have a happy Christmas, Kwanzaa, Hanukah, whatever boat you are
floating in.
