What changes in All Fourths
Every adjacent string is a perfect fourth apart, removing the major-third break between the G and B strings.
Make the tuning sound intentional
Play one major scale pattern across three string sets and notice how the fingering repeats without adjustment.
Shape tip: Scale and arpeggio shapes repeat consistently, but standard open chords must be relearned on the top two strings.
Retune to E A D G C F safely
The top two strings rise by one semitone; use appropriate gauges and tune them gradually.
Change one string at a time, approach the target pitch gradually and recheck every string after the neck settles. Stop if a string feels unusually tight, the bridge lifts or the instrument reacts unpredictably.
Turn the open strings into music

Some shapes may still work, but a interval tuning changes at least part of the fretboard. Start with the open strings, simple drones and the shape guidance on this page.
