→= 7ed8/5 (demonstrated to work but awaiting approval: Had the number of equaves counted from the colors in the video — instead use the number of octaves from the sound |
Got approval for 8ed4/3 and 60edf mappings; revise 7ed8/5 mapping as instructed |

[[Bryan Deister]] has demonstrated a mapping of [[60edf]] using a [[5L 1s (3/2-equivalent)]] scale having a 11:5 step ratio, in [https://www.youtube.com/shorts/h4tF_w2nIcY ''60ed(3/2) improv''] (2025). It takes advantage of nearly equal errors in the 2nd and 13th harmonics and a near-just 7th harmonic to make the (rightward) generator a near-just tridecimal 2/3-tone (~[[14/13]]), as 11\60ed3/2, and three of these yield the sound of a classic major third (as 33\60ed3/2), although ~[[5/4]] itself is mapped inconsistently to 32\60ed3/2. The range is a bit over five fifths with a moderate upwards slope, but at the cost of missing a few notes in each fifth. | [[Bryan Deister]] has demonstrated a mapping of [[60edf]] using a [[5L 1s (3/2-equivalent)]] scale having a 11:5 step ratio, in [https://www.youtube.com/shorts/h4tF_w2nIcY ''60ed(3/2) improv''] (2025).

[[Bryan Deister]] has demonstrated a mapping of [[7ed8/5]] using a [[ | [[Bryan Deister]] has demonstrated a mapping of [[7ed8/5]] using a [[1L 1s (8/5-equivalent)]] scale having a 5:2 step ratio and rotated to proceed right and up, in [https://www.youtube.com/shorts/Ex3EKrUt8q8 ''7ed(8/5) improv''] (2025). Right by one key is 5\7ed8/5, which yields a near-just ~[[7/5]] but also gets mapped as a very flat (but still consistent) ~[[10/7]]; two of these yield a very flat octave (~[[2/1]]). Down-right by one key is 3\7ed8/5, which functions as a fairly sharp ~[[17/14]] and a very flat ~[[21/17]]. Up one key is 2\7ed8/5, which sounds like a near-just septimal whole tone (~[[8/7]]), but actual ~8/7 is instead inconsistently mapped to 1\7ed8/5, thus requiring 2\7ed8/5 to be mapped as a very sharp ~[[9/8]] or a fairly flat ~[[15/13]]. Superficially, the range appears to be slightly over five instances of 8/5, and the overall 8/5 slope is very gently upward; however, due to the rotated and very wide-stepping scale pattern, the actual range is over nineteen octaves (as demonstrated in the video by the production of some extremely high notes); proceeding in the normal rightward and slightly downward direction instead yields a scale of [[5L 1s (4096/625-equivalent)]] having a 5:3 step ratio. | ||
