'''Tas''' is a series of [[generator sequence]] scales generated by GS([[7/6]], [[8/7]]) or GS(8/7, 7/6). It may be treated as a pair of closely related series of scales, since changing the order of the generators slightly changes the structure of the scale. | |||
The name "Tas" was coined by [[Scott Dakota]], deriving it from "{{w|Archytas}}". | |||
