A GPDO^{[idiosyncratic term]} (geometric pitch division of the octave) or EDQ'^{[idiosyncratic term]} (equal division of the quatave) is a type of octave-repeating scale obtained by taking a segment from a geometric pitch sequence.

-An '''EDQ'''{{idiosyncratic}} (equal division of the [[quatave]]) is a type of [[GPS]] (geometric pitch sequence) scale. n-edq is a geometric series of pitches starting at [[2/1]] (1200{{cent}}) and multiplying the previous pitch by 2<sup>1/n</sup> each time. For example, [[1edq]] doubles the pitch each time with the sequence of cent values being {1200, 2400, 4800, 9600...} and sequence of ratios being {[[2/1]], [[4/1]], [[16/1]], [[256/1]]...}. [[1/1]] is not present within an EDQ scale, so either it is considered rootless, or another interval (typically [[2/1]]) is considered the root. The scale type was first described by [[User:CompactStar|CompactStar]] and the name EDQ was coined by [[User:R-4981|R-4981]].
