I was under the = impression that in this scenario, the instrument would hold tune well, = perhaps only slightly less well than a regularly serviced instrument on = which PR are not needed or performed. It's my experience that after you've raised pitch more than = about 20 cents (varies piano to piano), the tuning will not hold as = well, no matter how many times you go over it, as it would had the piano = been up to pitch when you started. It may also depend on how long the = piano stood at a lower pitch.=20 <<That brings up another point. How many technicians raise pitch in = increments in this case? I find no reason not to yank each string over = pitch by 1/3 of the flatness no matter how flat it is. String breakage = does not seem to be a problem, and 40-50 cents over is not unusual. = However in talking to those in our Syracuse chapter leaving the piano = below pitch, or raising in 10-20 cent steps until the proper pitch is = reached it most common. Any comments? Mike Kurta >> Nah, I pull it right up there, overshooting by about 25 - 33%. = If the piano is somewhat decrepit or the strings show a lot of rust, I = try not to yank. If it's really old (before 1900 or so) or gives = indications of not being able to "take" A440, I might leave it at A435, = where it was designed to be anyhow. Also, I tighten plate screws first = and seat strings on the bridges first on old pianos, just to break "rust = bonds" and jar them loose a little before I bring them up all that way. = I don't see the point in the increments method -- if something's gonna = go, it'll do it on your last increment, whether that's today or in 5 = years (assuming you quit raising pitch when something "goes"). = --David Nereson, RPT, Denver ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
