Open D Tuning Chords for Folk, Fingerstyle and Slide

Open D tuning (D A D F# A D) gives a deep D major chord on the open strings, with three D notes across the neck. Four strings change from standard, and open D tuning chords ring wide and long, which is why fingerpickers and slide players love it.

Why it sounds so big

The 6th string drops to a low D, and the open strings keep ringing under anything you fret higher up. Play a melody on the top two strings while the open low strings drone, and one guitar sounds like two.

Shapes worth knowing

  • Dsus4: open strings with the 3rd string at fret 1 (G).
  • D7: open strings with the 2nd string at fret 3 (C).
  • Dmaj7: open strings with the 2nd string at fret 4 (C#).
  • Minor: barre a fret and play the 3rd string one fret lower.
  • DADGAD: raise the 3rd string from F# to G and you are in another famous tuning.

Train the drone and the change

Open D, 5th fret (G) and 7th fret (A) are I, IV and V. ChordRunner hears the real chord through the microphone, so you can drill those three positions and keep the low strings ringing while you move.

The levels in ChordRunner

  • Intermediate: adds sus2 and sus4.
  • Advanced: adds 6th, 7th and 9th chords.

Common questions

How do I tune to open D?

From standard, lower the 6th string to D, the 3rd from G to F#, the 2nd from B to A and the 1st from E to D.

What is the difference between open D and DADGAD?

Only the 3rd string: F# in open D (a major chord), G in DADGAD (a sus4 sound).

How do you play a minor chord in open D?

Barre the fret and lower the 3rd string by one fret.

Which instruments work?

A USB MIDI keyboard, detected automatically, or a piano or guitar through the microphone. Everything runs in Chrome or Edge on a computer, tablet or phone.

How is this different from apps where you tap the screen?

Tapping trains your eyes and fingers on glass. Here you press real keys or fret real strings, and the game hears the actual notes, so what you practise is exactly what you will play on your instrument.
