I was hoping someone else would make your point Keith. If I had to do it, I would likely have been banned from this list because of my language choices. If the piano was 300 cents flat to start with, and you started raising pitch at A0, the upper treble would be about 400 cents flat by the time you got up there. Then you would need to pull the treble about 140 cents sharp for it to fall back to target pitch. Boy, that sure sounds like a reasonable approach. I do that all the time in one pass and get PDG tuning results also! This may just be the silliest thing I've ever read on this list. Silly! Crazy! Insane! Impossible (to end up a "good" tuning - or even anything even resembling a poor tuning)! I tuned a Yamaha G2 in a church yesterday that had been "tooned" four months ago. I was shocked. I had tuned the piano for several years about ten years ago, but not since. Yesterday was my first time in 7 years or so. It had always been fairly stable in the past - church keeps AC on. Most unisons on the piano were within a few cents of one another, but individual notes in the temperament section were up to 10 and 15 cents flat. And no way was it any sort of well temperament - the thing sounded WAY out-of-tune. The entire treble had some notes at pitch or even a little sharp, while a good dozen intermittent notes were up to 30 cents flat (all three unisons). I can think of no explanation for this other than someone who hadn't a clue about tuning pianos tried to tune it. Or perhaps a toddler with a tuning lever was allowed to crawl inside the piano. Or maybe...... wait a minute.......... how far is Florissant, MO from Tampa?
