25-EDD

Dot-Guide for 25-EDD instruments

25-EDD Fretboard is based on the formula (Scale_Length/(2^(x/25))). 25-EDD is the 3rd system in which incorporates the Armodue system, after of 16 & 23 EDDs :

25-EDD Superdiatonic Dot-Guide

The dots are in the places 5· 8· 11· 14· 17· 20· 25: 30· 33· 36· 39· 42· 45· 50: 55· visualizing clearly the MOSscale of 2L5s 5;3 Relation, 5 3 3 3 3 3 5.

But too, 25-EDD will be represented with the simple 5-EDD subset for dot-guide, denoting its "pentimmetric" essence with great impetus :

25-EDD equal-sized Dot-Guide

The dots are in the places 5· 10· 15· 20· 25: 30· 35· 40· 45· 50: 55·
