50-EDD

Dot-Guide for 50-EDD instruments

50-EDD Fretboard is based on the formula (Scale_Length/(2^(x/50))). Being more useful for your fingers, is recommendable a Short Bass Scale Length (818mm [32.2"]) for this 'golden cat'. Maybe for a first instance with it, a employment of the (Cliché ;) 2L3s Dot-Guide :

The dots are suited in the places 13· 21· 29· 37· 50: 63· 71· & 79· denoting its Golden Meantone of 8;5 Relation. For the fretboard, that is the 13:8 proportion, 13 8 8 8 13, but not uniquely, a second form for dotting approaches in better way the extense fretting over the fingerboard :

This dots are suited in the places 9· 17· 25· 33· 41· 50: 59· 67· 75· & 83· denoting the scale of 2L4s 9;8 Relation, 9 8 8 8 8 9.
