Dot-Guide for 23-EDD instruments



23-EDD Fretboard is based on the formula (Scale_Length/(2^(x/23))). 23-EDD guard relation with the superdiatonic dot-guide beside of 16-EDD, because adapts perfectly the Armodue theory, but like 1/3-tone 3;1 relation, like its parallel homologue in 17-EDD with 12-EDD :

The dots are in the places 4· 7· 10· 13· 16· 19· 23: 27· 30· 33· 36· 39· 42· 46: 50· denoting a scale of 2L5s 4;3 Relation, 4 3 3 3 3 3 4.

The dots are in the places 5· 9· 14· 18· 23: 28· 32· 37· 41· 46: denoting a scale of 3L2s 5;4 Relation, 5 4 5 4 5.

A last option for dot-guide, is visually more simple, but intrinsic:
23-EDD Fretboard 2.png
23-EDD 'El Intrínseco' Dot-Guide
The dots are in the places 5· 6· 11· 12· 17· 18· 23: 28· 29· 34· 35· 40· 41· 46: denoting a scale of 4L3s 5;1 Relation, 5 1 5 1 5 1 5.
