Well, Ron, nobody did, but David has a perspective, as do you, which is not "right" but self-informed, and so also not "wrong". I see no reason, presuming the piano's tunable in the first place, that it can't be left in an acceptable So, "acceptable" = "adequate" or "fine"? Which is it? Do these words mean nothing? Is there no distinction? state of tune after a pitch raise. If, during the process, every realistic effort is made to pound the slack out of the back scale, followed by a real attempt to leave a stable string as you typically would, there's no reason you shouldn't end up with a piano as in tune as if you hadn't done a pitch raise. Can you substitute the word "stable" in place of "in tune" and make the same flat claim? (no pun intended) I agree with everything else you say, but I don't know what kind of tuning you are describing. Cheers, P That's the de-fuzzifier. You can leave the piano reflecting your typical standard of tuning after even a substantial pitch raise. How long it will stay that way depends mostly, in my experience, on how well you were able to equalize segment tensions on both sides of the bridges. Some techs have no conception of this, and some are fairly good at it. I've done half-to-full semitone pitch raises, with instructions to call for another tuning when it becomes obvious it's needed, and tuned the piano two years later no more off pitch than a stable piano tuned six months ago. I've also had them quite rough in a month, indicating I hadn't gotten segment tensions equalized as I had tried, even though the piano was in good tune when I left. I think two weeks is rushing it some for the follow up. A month is more reasonable to me, or when it sounds like it needs it. But that's my call. So, as usual, it depends.
