Hi Ron, Back in the bad old days when I was doing what Roger Jolly recommended (i.e. seating strings with a small hammer and using a hammer shank as a "drift") I never came across a string that went up in pitch. Some strings would not change pitch, and even in a single unison there were differences of zero to 35 cents among the three strings. I took a lot of measurements because I was hoping to create a "guesstimate" of how much to go beyond A440, seat the strings, and end up near A440. I think coils may squirm for many years. Certainly when I tighten them stability is improved. Too bad we don't live longer--so we could see the results of our (performed in good faith) actions 20 years later. Again with coils some strings seemingly don't change pitch even when they clearly have moved to tighter coils--and others may drop up to 150 cents. Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.P.T.
