Revision as of 07:42, 19 October 2025 by Lucius Chiaraviglio (talk | contribs) (Add ed8/5 Lumatone mappings, starting with Bryan Deister's Lumatone mapping for 7ed8/5)

This page is for Lumatone mappings for non-octave tuning systems. Identifying a temperament for non-octave tunings will be difficult due to lack of exploration compared to octave temperaments, so that is currently not a factor for separation of pages.

Unnamed Temperament Lumatone mappings ED4/3

8ed4/3 (demonstrated to work but awaiting approval)

Bryan Deister has demonstrated a mapping of 8ed4/3 using a 1L 4s (4/3-equivalent) scale (oriented nearly vertically) having a 4:1 step ration, in 8ed(4/3) improv (2025).

Unnamed Temperament Lumatone mappings ED3/2 (EDF)

60edf (demonstrated to work but awaiting approval)

Bryan Deister has demonstrated a mapping of 60edf using a 5L 1s (3/2-equivalent) scale having a 11:5 step ratio, in 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.

Unnamed Temperament Lumatone mappings ED8/5

= 7ed8/5 (demonstrated to work but awaiting approval

Bryan Deister has demonstrated a mapping of 7ed8/5 using a 3L 2s (8/5-equivalent) scale having a 3:1 step ratio, in 7ed(8/5) improv (2025). Right by one key is 3\7ed8/5 to yield a slightly flat neutral third (~11/9]]), which means that two of them make a mildly flat fifth (~3/2), while down-right by one key is 1\7ed8/5, which is a somewhat wide diatonic semitone (~16/15), which means that Up is 2\7ed8/5, which is a near-just septimal whole tone (~8/7). (Caution: These intervals have not been checked for consistent mapping.) The range is nearly five instances of 8/5, and the 8/5 slope is gently upward.
