>Equal-tempered scales are examples of geometric series, which are
>self-similar. 12-tet (mistakenly attributed to Bach) is discussed in terms of
>several "lucky" number-theoretic near-coincidences, such as 3^12 ~= 2^19 and
>5^3 ~= 2^7. The Pierce scale illustrates the near-coincidences 5^13 ~= 3^19
>and 7^13 ~= 3^23. A footnote remarks, "This patient listener, who has served
>as a subject in musical tests involving the Pierce scale, shows a stubborn
>preference for compositions written in well-established traditional scales."
