Pitch Raising

[Farrell]

I believe many have wrote that a splice in the speaking section does not
usually cause audible trouble. Especially, on an old upright, I would not
give any concern to it. You may need to remove some winding from the string
to get enough core exposed to do the splice. Again, on your piano, it is
unlikely that you are going to be troubled with degraded string tone
resulting from this procedure. I do this on older/poorer quality pianos
sometimes. And at worst - it will sound bad and you will need to replace the
string - nothing lost - you even gain, because now you will be a better
string splicer!
