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. <a = href="https://www.moypiano.com/resources/#archives"></a> <o:p></o= :p> Ah... an interesting change of directions to = this thread.  And I assume we are not refering to the string coupling = phenomena which I think several of us find reason to question to some degree = anyways. I've been increasingly scratching my head about how the three strings of = a unision affect each other while under adjustment. = <o:p></o:p> I know this sound totally out of there... but = I just keep getting the feeling that they somehow affect each other right at = the bridge... but perhaps its just really the backscale. Whether its my own = tuning technique or whatever... it seems that after tuning the center string, = if I tune the left string... the center string drops...if it moves at = all,  but if tune the right string the center rises or stays the same. I dont = really have any explaination for this and it strikes me as very curious. I've = checked this with both my ETD's as well... same pattern. I've tried tuning the right = string first, then the center and then the left... but both seem to pull the = right string downwards and it ends up costing too much time.... same thing in reverse = if I tune the left string first. <o:p></o:p> I know others report that they dont get this = kind of thing to happen at all, so perhaps it has something to do with tuning = hammer technique as well ? <o:p></o:p> RicB           <o:p></o:p> -- Richard Brekne RPT, N.P.T.F.
