List: Our newest Steinway "D" (3.5 years old) has always had a strong beat at the 10th partial on G-2. When the unison is otherwise as solid as it can be there is a +/- 2 beat per second at the 10th partial. It's always been there and fortunately pianists have never complained. Yesterday I had a couple of extra minutes so I measured some partials. On one string the 10th partial was 4.6 cents flatter than the other two strings. This is a 21-ga. unwrapped string. I measured the 8th partial and they were quite close on all three strings. Matching the 10th partial using a SAT makes quite a bad unison. Matching the 8th (or any others) makes a good unison. What would make one string have one flat partial? More inportantly, what is the fix? I thought about putting on a new string but unless I have pretty good evidence that this is the fix, I don't want to thread that under the bass strings and fight the tuning of it for a couple of weeks and not have it help.
