The four pillars of Xen theory are: - Just Intonation (JI) - Equal Divisions of the Octave (EDO) - Moments of Symmetry (MOS) - Temperaments
The four pillars of Xen theory are:


With EDOs, MOS, and temperaments, it’s important to know that although these concepts are all presented within the same context, they can exist separately or all within the same system.
* Just Intonation (JI)
* Equal Divisions of the Octave (EDO)
* Moments of Symmetry (MOS)
* Temperaments
 
With EDOs, MOS, and temperaments, it’s important to know that although these concepts are presented within a unified context, they exist as modular components.

In essence, JI is when intervals can be defined as frequencies that align and form whole number ratios. The tonality diamond is the conceptual layout of an odd-limit.

A nice way to lay out chord progressions is through a tonnetz lattice. Tonnetz originates from Neo-Riemannian Music Theory and the Mathematical toys of figures like Euler. [https://generalizedtonnetz.nickvuci.com/ Play with Vuci’s Generalized Tonnetz here]. 1. Input the EDO, here we do 12edo 2. Input the intervals for a minor triad, X: 7, Y: 3 3. For the diatonic scale, input the relative scale degrees in the drop down as “2,2,2,1,2,2,1” (which is MOS 5L 2s 2:1) 4. Highlight “0” if you want to 5. Input the minor triad for the red chord overlay: 0,3,7 6. Input the major triad for the blue chord overlay: 0,4,7 7. Then click on triangles and try out that progression in your DAW.
