This diagram shows where the notes of C major fall on a guitar fretboard in Fourths Tuning (EADGCF) versus a fretboard in Standard Tuning (EADGBE). I’ve extended the main pattern across the boundaries of the two fretboards so you can see how it repeats in space. The red dots show how the pattern is pushed up a fret on the two highest strings in Standard Tuning.
