<html> <body> Hi Richard,                     Lifting and leveling the strings definitely helps on new pianos, in a big way. A gentle massage just in front of the bridge pin, with a hammer shank, at the agle of the bridge pin, also helps. Gentle does not mean forcing down wards. Hope this helps.

Here's the scenario.  I'm working on a newer or rebuilt piano with tight pins and still relatively stretchy strings.  I'm trying to stabilize the instrument, but it's being stubborn.  I'm having to be more aggressive with my tuning technique, i.e., in order to settle the pitch I have to first pull the string higher than I like in order to move the tight pin and then allow the stretchy string to settle back to the pitch I want.  As I move up the piano, the pitch  behind me tends to creep higher, sometimes to the point I have to retune the note below.  I'm not a pounder, so I don't think that I'm beating the piano too hard.  I'm not trying to pitch raise/lower the piano, just give it a good solid tuning. What can I do to prevent this "phenomenon?"  Does anyone else experience this?  What is the cause?
