Short Answer
DADGAD tuning is an open modal tuning for six‑string guitars, tuned D‑A‑D‑G‑A‑D from low to high. It yields a suspended‑fourth sonority that encourages drone‑based accompaniment, making it popular in folk, Celtic, and acoustic benefit‑concert settings.

Etymology / Origin
The term DADGAD derives directly from the pitch sequence of the strings. The tuning emerged in the early 1960s among British folk guitarists such as Davey Graham, who sought a resonant, modal sound suited to Celtic melodies. Graham’s 1962 recording of “She Moved Through the Fair” popularised the tuning, which later spread to rock and world‑music contexts.
How It Works
In an acoustic setting, the open strings of DADGAD create a sympathetic drone that reinforces the fundamental frequencies of the guitar’s soundboard. This enhances sustain and projection, valuable in large‑room benefit concerts where amplification may be limited. The suspended‑fourth interval reduces harmonic tension, allowing vocalists and other instruments to blend smoothly during charity performances.

Step‑by‑Step / How to Play
- Start with standard tuning (E‑A‑D‑G‑B‑E).
- Lower the 6th string from E to D.
- Lower the 2nd string from B to A.
- Leave the 5th, 4th, 3rd, and 1st strings unchanged (A‑D‑G‑D).
- Check intonation with a tuner; ensure each string rings clearly.
- Practice the basic chord shapes listed above, focusing on smooth transitions.
- When playing in a charity setting, emphasize open‑string drones to fill the acoustic space.
Common Variations
- DADDAD – adds a fifth on the 2nd string (A‑D‑D‑G‑A‑D) for a stronger root.
- DADGAD# – raise the 3rd string to G♯ for a brighter modal flavor.
- Low D DADGAD – use a heavier gauge on the 6th string for deeper resonance in large venues.
Common Mistakes
- Neglecting to re‑tune the 2nd string; leaving it at B defeats the drone effect.
- Strumming with a heavy pick that masks the subtle overtones of open strings.
- Applying standard‑tuning chord fingerings without adjustment, leading to muted notes.
- Forgetting to check string tension after tuning; overly loose strings can buzz in live settings.
Notable Examples in Songs
- “The River” – Bruce Springsteen (acoustic benefit performance)
- “One Day Like This” – Elbow (unplugged charity concert)
- “Tears in Heaven” – Eric Clapton (acoustic tribute for charitable cause)
- “Hallelujah” – Jeff Buckley (live acoustic fundraiser)
- “Do They Know It’s Christmas?” – Band Aid (acoustic rendition for famine relief)
FAQ
Can DADGAD be used on electric guitars for charity gigs?
Yes, the tuning works on any six‑string instrument, but acoustic guitars provide the natural drone that benefits unamplified benefit venues.
Do I need a capo with DADGAD for different key songs?
A capo can shift the tonal centre while preserving the drone quality, allowing you to play songs in various keys without relearning chord shapes.
Is DADGAD suitable for beginners in charity performances?
It is classified as intermediate because it requires retuning and new fingerings, but the open strings simplify strumming patterns for novices.
How does DADGAD affect vocal accompaniment in a fundraiser?
The suspended‑fourth harmony creates a neutral backdrop that supports a wide range of vocal styles, helping singers stay in key during live charity sets.
What maintenance is required after frequently retuning to DADGAD?
Check string tension and intonation regularly; occasional neck relief adjustments may be needed if the guitar is tuned down often for low‑D setups.
