Hi all, I had an opportunity today to check this out. Note d2 on a sherlock-Manning serial # 18998 54" upright. Measurements made with Reyburn Cyber tuner 22 degrees C. and 32% humidity. Each string was "zeroed" with a blank tuning record, after tuning aurally for the best compromise between the strings. round zero at -14.86 (iron wound) partial 1 2 3 4 5 6 7 8 0 3.49 5.92 3.31 6.17 9.04 -20.86 11.94 hex zero at -8.76 (copper wound) 0 2.07 5.02 1.83 -10.17 5.41 -23.63 8.99 It would appear that inharmonicity is lower in the hex core string. Or perhaps it is the iron winding? For those that might understand the I subscript c reading from Pianalzyer was: round 0 0.83 0.41 0.16 0.28 0.19 0.17 0.18 hex 0 1.96 0.85 0.35 0.27 0.19 0.20 0.18 I don't think there is a way to *zero* the pitch difference with pianalyzer. I don't really understand the second set of readings myself. Comments? Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.M.T., R.P.T.
