What is DADGAD tuning?

DADGAD tuning changes all six strings to D-A-D-G-A-D (low to high). When strummed open, it produces a Dsus4 chord — a suspended chord that sounds neither major nor minor, giving it a hauntingly open quality.

What scales sound best in DADGAD?

D Mixolydian and D major pentatonic are natural fits. The D Dorian mode creates a beautiful Celtic feel. Scales rooted on D work best because they can use the three open D strings as drones.

Is DADGAD good for songwriting?

Absolutely. DADGAD is a songwriter's dream tuning. Its open, ambiguous quality inspires new chord shapes and melodic ideas you'd never find in standard tuning. Many acoustic singer-songwriters use it as their primary creative tuning.

About DADGAD Tuning

DADGAD tuning creates an open Dsus4 chord when strummed open, producing a hauntingly beautiful, droning sound that has become synonymous with Celtic folk music and modern acoustic songwriting. The tuning's natural resonance and overtones make even simple fingerpicking patterns sound rich and complex.

Popularized by Davey Graham in the 1960s and later championed by Pierre Bensusan and Jimmy Page, DADGAD has become one of the most beloved alternate tunings for acoustic guitarists. Its suspended quality — neither clearly major nor minor — creates an ethereal, meditative atmosphere that invites exploration. The tuning excels at creating drone-based arrangements where open strings ring against fretted notes.
