c13.s1.13

The distance C c was divided into half at F, and the distance C to F into nine equal parts, and F to c into thirteen equal parts by frets; at least, that was the intention. Actually C to F contained 145 mm., of which 1/9th = 16 1/9, while the distances between frets really varied from 15½ to 16½. The distance F to C was 146½ mm., of which 1/13th is 11·27 mm., while the distances between the frets varied from 9½ to 13½ mm. as well as I could measure. This gave very varying values to the s'ruti intervals. From C to F they varied from 45 to 73 cents, from F to c they varied from 37 to 84 cents. The intention, I presume, was to make them as nearly equal as possible or 54 6/11 cents each.
