Dot-Guide for 11-EDD instruments

11-EDD Fretboard is based on the formula (Scale_Length/(2^(x/11))). With its special characteristics, the 11-EDD is like the never knowned neighborn. This system show us a type of harmonic interrelations not frequent, and with this dot-guide show us a similitude with 8-EDD, like "1/3-tone" of that. The simpleness is in much cases the best root for understand unknowned things :
