Short Answer
Open D tuning is an alternate guitar tuning where the strings are tuned to D–A–D–F#–A–D (low to high), forming a D major chord when strummed open. This tuning simplifies chord shapes, enhances resonance, and is a favorite among slide guitarists and fingerstyle players. It opens up a world of rich, droning harmonies and is featured in countless folk, blues, and rock classics.

Etymology / Origin
The term “open D tuning” derives from the fact that strumming all six strings without fretting any notes produces a full D major chord. This tuning belongs to a family of “open” tunings, each named after the chord they form when played open. The origins of open D are deeply rooted in the American South, particularly in the Delta blues tradition of the early 20th century. Musicians like Charley Patton, Son House, and Robert Johnson often used open tunings to facilitate slide guitar playing, where a glass or metal slide is used to fret notes, creating a smooth, vocal-like tone. Open D (and its close relative, open E) became a staple for slide guitarists because it allowed them to play entire chords with a single finger barre, freeing the other fingers for melodic embellishments.
The tuning also found its way into folk and country music, notably through the work of artists like Joni Mitchell, who used it extensively for its droning, harp-like qualities. Mitchell’s innovative use of open D in songs like “Big Yellow Taxi” and “A Case of You” demonstrated the tuning’s potential beyond blues, inspiring generations of singer-songwriters. Today, open D remains a favorite for its versatility, used in everything from rock (The Rolling Stones’ “Street Fighting Man”) to modern indie folk (Mumford & Sons’ “The Cave”).
How It Works
In standard tuning (E–A–D–G–B–E), the guitar is tuned in fourths, except for the interval between the G and B strings, which is a major third. Open D tuning alters this to D–A–D–F#–A–D, creating a D major triad across the open strings. The intervals are: root (D), fifth (A), root (D), major third (F#), fifth (A), root (D). This means that any fret where you barre all six strings will produce a major chord, with the root note determined by the fret position. For example, barring at the 5th fret yields a G major chord, and barring at the 7th fret yields an A major chord. This is because the open strings are tuned to a D major chord, and moving the barre up the neck transposes the chord chromatically.
The tuning also creates a rich, droning effect because of the multiple D and A strings. The three D strings (6th, 3rd, and 1st) provide a strong root presence, while the two A strings (5th and 2nd) add a powerful fifth. This makes open D ideal for fingerstyle patterns that incorporate open strings, as well as for slide guitar, where the slide can glide across all six strings to produce full chords. Additionally, the tuning lowers the string tension, making it easier to bend strings and perform vibrato.
Chord Shapes and Diagrams
While open D simplifies major chords, other chord types require specific fingerings. Below are the most essential chord shapes. All diagrams assume the guitar is in open D tuning (D–A–D–F#–A–D).
| Chord | Fingering |
|---|---|
| D major (I) | Open strings (0-0-0-0-0-0) or barre at 12th fret |
| G major (IV) | Barre all strings at 5th fret |
| A major (V) | Barre all strings at 7th fret |
| B minor (vi) | Barre at 2nd fret, but mute the 1st string; or play 2nd fret on 6th, 5th, 4th strings, 2nd fret on 3rd string, open 2nd string, 2nd fret on 1st string (x-2-2-2-0-2) |
| E minor (ii) | Barre at 2nd fret, but fret 1st string at 2nd fret and 2nd string at 2nd fret? Actually, E minor in open D: 2-2-2-2-2-2 gives E minor? No, barre at 2nd fret gives E major (since open D is D major, barre 2 gives E major). For E minor, you need to lower the third. One common shape: 2-2-2-0-2-2 (fret 6th,5th,4th at 2; 3rd open; 2nd and 1st at 2). That gives E minor. Alternatively, 0-2-2-0-2-0? Let’s provide a reliable shape: 2-2-2-0-2-2. |
| F# minor (iii) | 4-4-4-2-4-4 (barre 4th, but 3rd string at 2nd fret) |
| D7 (I7) | 0-0-0-3-0-0 (fret 3rd string at 3rd fret) or 0-0-0-5-0-0 |
| G7 (IV7) | 5-5-5-8-5-5 (barre 5th, 3rd string at 8th) |
For a quick I–IV–V progression in D, simply play open D, barre at 5th (G), and barre at 7th (A). To add a minor chord, use the B minor shape above. Experiment with partial barres and open strings to create lush, droning textures.
Step-by-Step: How to Play in Open D
- Tune your guitar to open D. Starting from the 6th string (low E), tune down a whole step to D. Leave the 5th (A) and 4th (D) strings as they are. Tune the 3rd string (G) down a half step to F#. Tune the 2nd string (B) down a whole step to A. Tune the 1st string (high E) down a whole step to D. Use a chromatic tuner for accuracy.
- Familiarize yourself with the open sound. Strum all strings open to hear the D major chord. Play each string individually to ensure they are in tune and resonate clearly.
- Learn the basic barre chord positions. Practice barring all strings at the 5th and 7th frets with your index finger. Apply even pressure and listen for any muted or buzzing strings. Adjust your finger position until all notes ring out.
- Practice the I–IV–V progression. Strum open D, then barre at 5th (G), then barre at 7th (A). Use a simple down-up strumming pattern. Once comfortable, try arpeggiating each chord.
- Incorporate minor chords. Learn the B minor shape (x-2-2-2-0-2) and the E minor shape (2-2-2-0-2-2). Practice transitioning between major and minor chords in common progressions like D–Bm–G–A.
- Experiment with slide. If you have a slide, place it lightly over the strings at the 12th fret and strum. Glide the slide up and down the neck while maintaining even pressure. The tuning’s open chord makes slide playing intuitive.
- Explore fingerstyle patterns. Use your thumb for the bass notes (6th, 5th, 4th strings) and fingers for the treble strings. Let open strings ring out to create a harp-like effect. Try patterns like Travis picking or simple arpeggios.
Common Variations
- Open D minor (D–A–D–F–A–D): Lower the 3rd string from F# to F. This creates a somber, minor tonality and is used in songs like “The End” by The Doors.
- Open D with a capo: Placing a capo at the 2nd fret in open D effectively gives you open E tuning (E–B–E–G#–B–E), a favorite of Duane Allman. This allows you to use open D shapes while playing in the key of E.
- DADGAD tuning: Often confused with open D, DADGAD (D–A–D–G–A–D) is not a full major chord but a Dsus4 chord. It is widely used in Celtic and world music for its ambiguous, droning quality.
- Open D with a dropped 6th string (C–A–D–F#–A–D): Some players lower the 6th string to C for a deeper bass, creating a C6/9 chord when open. This is less common but offers unique voicings.
Common Mistakes and Troubleshooting
- String buzzing when barring: Ensure your barre finger is close to the fret wire and apply even pressure. If buzzing persists, check your guitar’s action and neck relief. Lighter gauge strings may also help.
- Unwanted string noise: In open tunings, sympathetic vibrations can cause strings to ring out unintentionally. Use your fretting hand’s fingers to lightly mute strings that shouldn’t sound, and practice palm muting with your picking hand.
- Intonation issues: Changing string tension can affect intonation. After tuning to open D, check the tuning at the 12th fret harmonic and adjust your guitar’s intonation if necessary. A professional setup is recommended if you plan to use this tuning frequently.
- Difficulty transitioning from standard tuning: Spend time playing simple melodies and chord progressions exclusively in open D to build muscle memory. Start with songs you know well in standard tuning and adapt them.
- Over-reliance on barre chords: While barre chords are convenient, explore partial chords and open-string drones to add variety. For example, instead of barring for G, try fretting only the 6th, 2nd, and 1st strings at the 5th fret while leaving the others open.

What are some easy songs in open D tuning?
Beginner-friendly songs include “Big Yellow Taxi” by Joni Mitchell, “The Cave” by Mumford & Sons, and “Ain’t No Sunshine” by Bill Withers. These use basic barre chords and open-string drones.
Do I need a special guitar for open D?
No, any acoustic or electric guitar can be tuned to open D. However, you may need to adjust the truss rod or intonation if you plan to keep the guitar in this tuning permanently, as the altered string tension can affect the neck.
