What changes in Major Thirds
Each string is a major third above the previous one, so note names and chord shapes repeat every three strings.
Make the tuning sound intentional
Find every E major triad in one position, then move the same shape exactly three strings higher.
Shape tip: Build triads inside small four-fret areas and exploit the repeated E, G-sharp and C pitch classes.
Retune to E G# C E G# C safely
Use a custom balanced string set because several strings move far from standard pitch.
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
