Today I tuned an older Kawai "K20" studio piano. The bass could not be tuned smoothly. I was tuning aurally and finally when I got to A2 decided to check the partials with my SAT. I set the 4th partial of A2 to A4. There was still a lot of beating going on. I decided to measure the 6th and 8th partials to see how sharp they were causing all that racket. They were flat! How do partials that high get flat? That is a consumate pain to tune and I do it a couple of times a year. Any clues????? dave _______________________________________________ David M.
