Hi, Keith!

I think this technique was first advocated by "Bart" Christofori almost
300 years ago and has more or less been SOP ever since! It is especially
effective on older, neglected instruments where you can see a substantial
amount of corrosion on the strings, pins, pressure bar (upright), capo
bar, agraffes, and even bridge pins. As you first lower the tension on the
string. you can often hear a slight "tick" as it breaks free from the
bearing point. I have no doubt at all that this technique has saved me
numerous broken strings over the years. Note that I still employ this
technique on older, neglected instruments, even though the first thing I
do is to apply a small amount of a high-quality lubricant like Protek, to
those same bearing points. All I can say is that the technique has worked
for me. A few years ago I ran into real piece if "bad news" (thanks to a
refferal) that was 700(!) cents flat and hadn't been tuned in over forty
years. Although it took me more than one session, by employing the above
technique, I eventually got the piano back to a stable A-440 without
breaking a single string. Hey, That even surprised ME! When I finished
up and the lady paid me, she told me "that the piano had never sounded
so good" and that she would be sure to call me again "Next time". As I
walked out her front door, I thought to myself "Lady, I'm probably not
even going to be ALIVE another forty years from now"!
