A modal tuning built around D and A
DADGAD creates open D and A drones without fixing the third of the chord, which makes the tuning flexible for modal harmony, Celtic accompaniment and fingerstyle arrangements.
Three strings change from Standard: sixth-string E2 to D2, second-string B3 to A3 and first-string E4 to D4. Tune those strings deliberately, then verify the unchanged center strings.
Four clear steps

Frequently asked questions
Which strings change for DADGAD?
From Standard, lower the sixth and first E strings to D and lower the second B string to A.
Is DADGAD a D major tuning?
Not exactly. The open strings omit F♯, the major third, so the tuning is modal rather than a fixed open D-major chord.
