This is a flipped version of Double-Bosanquet which results in octaves being closer to horizontal. The step shape normally mapped to major seconds is here mapped to neutral seconds. [[Bryan Deister]] has demonstrated this mapping in two very different compositions: [https://www.youtube.com/shorts/AkXCy6bTrgY ''31edo groove''] (August 19, 2025) and (with a different note 0 position and radically color pattern) [https://www.youtube.com/shorts/5W7ykrMjR1g ''31edo improv''] (October 28, 2025). | This is a flipped version of Double-Bosanquet which results in octaves being closer to horizontal.

Since the fifth ~[[3/2]] of [[31edo]] is 18\31, [[31edo]] lends itself well to [[mothra]] temperament, in which the rightward generator 6\31 is ⅓ of a fifth, corresponding to a near-just septimal major second ~[[8/7]]; four of them make a flat septimal major sixth ~[[12/7]]. [[Bryan Deister]] demonstrates this mapping in [https://www.youtube.com/shorts/YX60a8h2hOs ''31edo improv''] (2026-10-16). The range is about 5¾ octaves, with a gentle upwards slope and some repeated notes to mitigate vertical wraparounds. | |||
