Again, I'd call it 1/8 (to myself), and I'd certainly use it. I think a true 1/7 comma wouldn't be good for his repertoire - wolf and bad M3s too noticeable. If he likes the 1/8 comma, I'm not going to quarrel with him <G>. It just occurred to me I had a document from Bill Bremmer on mild mean tone. It confirms what I have been saying. The 1/8 comma figures are almost exactly what Tim Farley provided. (I hope the chart following translates okay. It is a copy and paste from a Word document, so it may screw up in many email programs. In any case, it shows offsets for 1/7 comma the same as what I calculated, and 1/8 comma within 0.1 cent of what Farley provided). Perhaps somebody should tell Peter Serkin. Or perhaps not.
