Pulling the string = sharp is called overpull. If you end up at your targeted pitch, your = "slight roll to the right" simply must be an appropriate overpull to = compensate for the amount the piano will go flat after the pitch raise = pass. I don't think it can really vary from that. Terry Farrell =20 ----- Original Message -----=20 From: David Ilvedson=20 To: pianotech=20 Sent: Wednesday, November 07, 2001 5:52 PM Subject: Re: Oops?

I also don't overpull on new pianos where = strings are not likely to break... David I. Hmmmmm. Why do you not use any overpull to get the piano to pitch?

I am in the minority, but I don't raise above pitch at all...If = -100 cents, I take a my FAC readings with those notes at correct pitch = then bring each string up to a correct pitch as per SAT from A0 to = C8...if the tenor isn't as flat as the rest of the piano it doesn't get = raised any higher than any other part of the piano. So when I go = through it a second time it is about 10 to 15 cents flat (I don't really = care where...the piano decides that but it isn't anywhere near 30 cents = flat!) and I go through it again to pitch. The bass is now reasonably = stable and a quick 3rd time through the tenor/treble and I'm done with = the initial tuning...see ya in 3 to 6 months...am I concerned about the = quality or stability of the tuning? I don't think so...I didn't let it = go for 15 years...it's not my problem...I don't use a temp strip, just = mutes and tuning unisons as I go...

Yes, but bear in mind that most of the time I use a more = conventional amount of stretch. The triple octave/double octave and = fifth comparison is only for when I wan the absolute maximum and = justifiable amount. =20 Once I get into the last part of the 7th octave, all bets are = off. But let's take a piano that is 1/2 step flat in the midrange. = That's 100%. Very often, such a piano is not evenly low in pitch. The = high treble may easily be 150% flat.
