To | To maximize your range while covering the full gamut, use the [[3L 10s]] (10:7 step ratio) scale generated by a submajor third (in between ~[[5/4]] and ~[[16/13]]) of 31/100, which functions as a slightly sharp tridecimal submajor third ~[[26/21]] and a near-just (only slightly flat) tricesimoprimal submajor third ~[[31/25]]. The temperament is related to [[submerged]] in that 11 generators stack to make the flat ~[[4/3]] (41\100, corresponding to the sharp fifth ~[[5/3]] of 100edo), but it misses most of the other intervals of submerged temperament. The range is just under 2½ octaves, which slope mildly upwards. | ||

== Unnamed rank-3 temperament == | |||
[[Bryan Deister]] has demonstrated a mapping for [[100edo]] that supports both a [[16L 4s]] scale (6:1 step ratio) and a flipped [[15L 2s]] scale (6:5 step ratio), in [https://www.youtube.com/shorts/gPbsSs4MFbQ ''100edo improv''] (2026). The rightward generator 6\100 functions as a near-just (only slightly flat) lesser vicesimotertial semitone ~[[24/23]] and a near-just (only slightly sharp) classic chromatic semitone ~[[25/24]]. Since 6 is not coprime with 100, an additional generator is required; since down-right 1\100 is used more often in the linked demonstration video, it can be considered the second generator; it functions as a sharp valinorsma ~[[176/175]] or a near-just (only slightly sharp major kirnbergerisma ~[[161/160]]. (Technically it could be used as a sole generator, but due to its small size, this would be very unwieldy. Also, technically the first generator 6\100 could be used as the sole generator for a rank-2 temperament with the octave divided into four parts, but this would be unwieldy for anything other than the aforementioned 16L 4s scale. The alternative upwards generator 5\100 is not co-prime with 100edo either, and would not work as the sole generator even with division of the octave into four parts.) The range (a bit over 1½ octaves) is even less than that of the [[12L 4s]] extra-expanded diatonic mapping, and the octaves slope upwards even more, but in exchange, this mapping enables easy fine adjustment of pitch and has a decent number of repeated notes to mitigate vertical wraparounds, while still having only a few notes of range chopped off in the corners. | |||
