Since [[56edo]] is a multiple of [[7edo]], it can be used with a mapping that divides the octave into seven parts in the manner of [[whitewood]], but with more accuracy due to having a much better fifth; in this case, the actual temperament is [[sevond]], which if restricted to the [[5-limit]] uses a generator of a mildly sharp fifth ~[[3/2]] and a period mapped inconsistently as a very flat classic whole tone ~[[10/9]] to 8\56, which 1/7-octave-reduces the generator to 1\56 (proceeding down), which functions as a very flat (and inconsistently mapped) chromium quartertone ~[[250/243]]. With higher prime limits, more accurate mappings are available — for instance, in the [[13-limit]], remapping the 1/7-octave period as a moderately sharp but consistently mapped large undecimal neutral second ~[[11/10]], and likewise remapping the 1/7-octave-reduced ~3/2 generator: technically as a very flat and inconsistently-mapped ~[[15000/14641]], but more practically as a slightly flat and consistently-mapped negustma ~[[78/77]]. [[Bryan Deister]] has used this mapping in [https://www.youtube.com/shorts/5j-TAkmdWqc ''56edo groove''] (2026). The range is a bit over four octaves, which slope upwards with the rows. | Since [[56edo]] is a multiple of [[7edo]], it can be used with a mapping that divides the octave into seven parts in the manner of [[whitewood]], but with more accuracy due to having a much better fifth; in this case, the actual temperament is [[sevond]], which if restricted to the [[5-limit]] uses a generator of a mildly sharp fifth ~[[3/2]] and a period mapped inconsistently as a very flat classic whole tone ~[[10/9]] to 8\56, which 1/7-octave-reduces the generator to 1\56 (proceeding down), which functions as a very flat (and inconsistently mapped) chromium quartertone ~[[250/243]].
