Catalog of rank-4 temperaments

(Redirected from Rastmic)
Jump to navigation Jump to search
This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

A rank-4 temperament has a period and three additional independent generators, for a total of four dimensions. Typical examples include 7-limit JI, full 11-limit temperament with a one-dimensional comma basis, and full 13-limit temperament with a two-dimensional comma basis.

Olympic (131072/130977)

Olympic is highly accurate yet easy to conceptualize and notate on the staff. It equates 33/32 with (64/63)2, and 36/35 with 1053/1024, reducing the four formal commas required for the 13-limit to two. Therefore it can be notated in chain-of-fifths notation with two additional set of accidentals, one for the septimal comma step, and the other for the aberschisma step. It can be viewed as the detemperament of cassaschismic that decouples the Pythagorean and septimal commas.
