Lumatone mapping for 25edo

Revision as of 08:10, 29 August 2025 by Lucius Chiaraviglio (talk | contribs) (Add Bryan Deister's Gariberttet + Magic mapping)

There are many conceivable ways to map 25edo onto the onto the Lumatone keyboard. However, it has 5 mutually-exclusive rings of fifths, so the Standard Lumatone mapping for Pythagorean is not one of them.

Antidiatonic

You can use the b val, which creates the 2L 5s Mavila mapping.

Blackwood

Since 25edo's flat fifth is very flat, even more than 16edo, better options exist for reaching consonant intervals easily, and the the Blackwood mapping is one option.

Luna

Or the Luna mapping, which puts the 5th and 7th harmonics in a neat line from the root.

Gariberttet + Magic

Bryan Deister has demonstrated a mapping of 25edo that functions for both Gariberttet compressed to 1L 3s (7:6 step ratio) and Magic 3L 4s (7:1 step ratio), both having rotated scales, in Waltz in 25edo (short clip) (2024), with both the Blackwood fifth ~50/33 and the Mavila sub-fifth ~25/17 in easy reach. The range is over nine octaves, although with a severe downwards slant.
