CGDGAD Guitar Tuning
CGDGAD sets the six strings from low to high to C G D G A D. Its low, droning and harmonically open voice works especially well for Celtic arrangements, G and C drones and solo acoustic guitar.

What changes in CGDGAD
A low C supports the DADGAD-like upper strings, creating strong C, G and D pedal tones.
Make the tuning sound intentional
Keep G and D ringing while moving the bass between C, D and E.
Shape tip: Use the sixth string as a changing bass under familiar DADGAD-style shapes.
Retune to C G D G A D safely
The sixth string drops four semitones; a heavier low string improves definition.
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

Can I use normal chord shapes in CGDGAD Guitar Tuning?
Some shapes may still work, but a celtic modal tuning changes at least part of the fretboard. Start with the open strings, simple drones and the shape guidance on this page.
Why do the strings go out of tune again after retuning?
Changing one string changes the total tension on the neck. Tune all six strings, wait briefly and repeat the process until every reference pitch remains stable.
