How to Read Guitar Scale Diagrams

Guitar scale diagrams show the pattern of notes to play a scale, and where the notes would appear on the fretboard.

A scale diagram represents the fretboard of a guitar. Just like a guitar tab, the bottom line of the guitar scale diagram represents the low E string.
