I have indeed noted this frustrating phenomenon. I'm guessing that if we were real observant we would probably note a correlation between this and the way the pitch changes while the string is being tuned, i.e., some correlation with how easily the string moves and "equalizes" under the hammer. Actually, the most frustrating times I can remember happened when I made a pitch DROP. You do the correction from 1-88 then, usually in the tenor section, you tune a center string--settling string & pin as always--only to find that it moves sharp, significantly, while you tune an outer string. I've noticed this much more so than movement after a pitch RAISE. Maybe it's something in my technique but I don't know what it could be. I'll bet, again, it is related to the ease with which the string renders under the vee/capo bar, through the bridge, etc. Alan R.

Have you ever had the first string you tuned drop suddenly as you were tuning the second or third to it, even after pounding the first string into what should have been adequate submission? Where did the pitch drop come from? There are only three remotely rational possibilities I can think of. One is from the back scale, which I consider most likely in spite of the pounding. Second is from the coil, which, interestingly enough, will often entertain you with a dramatic pitch drop if you tap on it a bit, but normally won't if you don't. Third is a highly localized structural failure affecting only one string. I'll take door number one, please.
