=== 44edo (demonstrated to work) === | |||
[[Bryan Deister]] has demonstrated a [[4L 4s]] mapping (6:5 step ratio) [[44edo]], in ''Buried Treasure - 44edo'' (2026) [https://www.youtube.com/shorts/Oi3v0c7jbjM (''<nowiki>[short clip]</nowiki>''], [https://www.youtube.com/shorts/ZOoiGuUA-9Y ''<nowiki>[short 2]</nowiki>'']). This mapping also functions as a very hard flipped superdiatonic mapping ([[7L 2s]], 6:1 step ratio with the small steps going up instead of down-right), a flipped antidiatonic mapping ([[2L 5s]] with 7:6 step ratio and expanded small step going right + up), and as a [[13L 3s (4/1-equivalent)]] mapping (with 6:5 step ratio, proceeding through the octave zig-zag). Right + down-right divides the octave into slices of 11\56; as an interval in its own right, this is the same as the minor third of [[12edo]], which functions as ~[[19/16]] and ~[[25/21]] (both being near-just). Down-right alone is 4\56, which is the [[Normal forms#Minimal_form|minimal form]] generator for [[Bidia]]; it functions as the classic diatonic semitone ~[[16/15]], the large septendecimal semitone ~[[17/16]], and the small septendecimal semitone ~[[18/17]] (which is inconsistently mapped), meaning that the charisma [[256/255]] and the semitonisma [[289/288]] are both tempered out; two of them make a rather sharp whole tone ~[[9/8]] (which is also inconsistently mapped); three of them (passing the quarter-octave) make a sharp classic minor third ~[[6/5]], while the afore-mentioned quarter-octave (12edo-style) minor third is about equally easy to reach; in contrast, the somewhat flat classic major third ~[[5/4]] requires two moves rightwards plus two moves upwards; four moves right reaches the rather flat fourth ~[[4/3]]; another move right and two moves upreaches the rather sharp fifth ~[[3/2]]. The range is a bit under 4¾ complete octaves (with some extra non-contiguous notes at each end), but unlike the normal antidiatonic mapping, the octaves alternate between near/far and mid or near and far (superimposed upon an overall upwards slope). | |||
