I must ask again, what exactly what you are referring to? How can I check this out? What is the author, the work, and the page? In Ellis' s translation of Helmholtz, "Sensations of Tone", the only tuning by Moore I see, is that of an harmonium, (not a piano) "tuned by one of Messrs. Moore & Moore tuners, kindly prepared for my examination." Ellis p 485. (line 7). Why would a tuner want to tune a historical tuning on a piano today that is derived from a tuning on an harmonium in in 18??. Since cents is an additive quantity, lets add up the results of Ellis's research in 1880. Looking at p485 line 5 which Ellis proclaims Broadwood's best. Here the total cents deviation from theoretical ET is 12 cents over 13 notes, or 12 intervals. For Moore it is 18 cents. For Broadwoods worst (line 2) it is over 50 cents. This piano though Ellis says was "Let stand unused for a fortnight ." (two weeks). Line 3 is close to 48 cents off. Line 4 is 14 Line 5 again is 12 cents..... off. Now lets measure one of your tunings, or more importantly one of my tunings in the same manor and see how close we me.... ---rm
