DADGAD Tuner: the complete guide
By Vivek Badoni, music teacher · Updated
This online DADGAD tuner opens with DADGAD selected. Three strings change from standard tuning, and the open strings ring out a shimmering Dsus4 chord, the sound of Celtic guitar, folk and atmospheric fingerstyle. Play any string and the tuner shows which it is and how far off you are.

How to tune to DADGAD
- Start in standard tuning and check the A, D and G strings.
- Lower the 6th string from E to D, an octave below the open 4th string.
- Lower the 2nd string from B to A, an octave above the open 5th string.
- Lower the 1st string from E to D, an octave above the open 4th string.
- Strum all six. The chord should ring evenly with no beating between strings.
Why DADGAD sounds the way it does
The open strings contain only D, A and G, the root, fifth and fourth of D, with no third. Without a third, a chord is neither major nor minor, so the same simple shapes work for songs in D major and D minor. Open strings ring against fretted notes, creating the drone-like, harp-like sound guitarists love.
Getting started in DADGAD
- Fret the 4th string at the 4th fret to add F♯ and give the chord a D major sound.
- Fret the 4th string at the 3rd fret instead to add F for a D minor sound.
- Move simple two-finger shapes up the neck and let the open D and A strings drone underneath.
