string seating/ was String massage

[Don]

Hi Patrick,

I would add tapping at the hitch pins and scaling, as well as lifting the
string on the tuning pin side of the agraffe. Use your favorite tool to
tighten the tuning pin coils as well. One recent piano that was over a year
old dropped a total of 130 cents at A4. It had been tuned 4 times during
the year.
