m →20edo (demonstrated to work but awaiting approval): Temperament. (same one as the max range mapping for 17edo, but not as well tuned here.) |
Both 20edo mappings: Got approval with instructions where to put note 0; fill out description (thanks to YourMusic Productions for pointing out skwares temperament for the second 20edo mapping) |

In this mapping, the octave can be interpreted as being divided into five parts (Blackwood temperament) or 4\20 or four parts of 5\20 (Diminished temperament). Octaves slope, as expected for a Blackwood mapping, but with plenty of repeated vertical notes, and the range is a bit over 5½ octaves. | ||

[[Bryan Deister]] has used | [[Bryan Deister]] has used a compressed [[Skwares]]) [[2L 1s]] (7:6 step ratio) mapping for [[20edo]], as demonstrated in [https://www.youtube.com/watch?v=BFUTeFs7Ycg ''20edo groove''] (2025). In the version of Skwares used for this, instead of substantially sharpening the undecimal major third ~[[14/11]] (or even a septimal major third ~[[9/7]]) to get a diatonic fourth ~[[4/3]] (by stacking and octave-reducing four generators), the undecimal major third (7\20) is near-just, and the fourth is very flat at 480{{c}} (corresponding to the Blackwood sharp fifth at 720{{c}}). Octaves are nearly level (sloping down very gradually), and the range is a bit over 11 octaves, which suggests dividing the keyboard into zones for different instruments. | ||
