Open D Tuning Guide and Online Guitar Tuner
Tune guitar to Open D (D-A-D-F#-A-D), hear a D major chord on the open strings, and launch a preset microphone tuner.
What Is Open D Tuning?
The six open strings form a complete D major chord with strong root and fifth drones.
Open D Tuning uses D2 - A2 - D3 - F#3 - A3 - D4 from the lowest sixth string to the highest first string.
Change from standard
From standard, lower both E strings to D, lower B to A, and lower G to F#; A and D remain unchanged.
Sound and feel
The six open strings form a complete D major chord with strong root and fifth drones.
Common uses
Slide guitar, fingerstyle, folk, blues, songwriting, drones, and one-finger major chords.
How to Tune a Guitar to Open D Tuning
Make small adjustments, let each string settle, and repeat the complete guitar after the neck tension changes.
- 1
Start near standard tuning
Check that the current string pitches are known before making larger changes.
- 2
Follow the target sequence
From standard, lower both E strings to D, lower B to A, and lower G to F#; A and D remain unchanged. The final low-to-high targets are D2 - A2 - D3 - F#3 - A3 - D4.
- 3
Use the microphone tuner
Open the preset tuner, play one string at a time, and move the cents reading toward zero.
- 4
Recheck every string
Retuning changes total neck tension. Repeat the sequence until earlier strings no longer drift.
What Open D Tuning Is Used For
Slide guitar, fingerstyle, folk, blues, songwriting, drones, and one-finger major chords.
Slide guitar
A straight slide across one fret produces a major chord when intonation is centered.
Fingerstyle drones
Open D and A strings can ring beneath moving melody and inner voices.
Simple major chords
A full barre moves the open D major shape to other major roots.
Songwriting
The resonant open chord suggests voicings and melodies that do not appear naturally in standard tuning.
Open D Tuning vs. Standard Guitar Tuning
The same guitar can use either setup, but open strings, tension, chord shapes, and usable drones change.
| Open D Tuning | Standard tuning | |
|---|---|---|
| Open strings | D2 - A2 - D3 - F#3 - A3 - D4 | E2 - A2 - D3 - G3 - B3 - E4 |
| How to change | From standard, lower both E strings to D, lower B to A, and lower G to F#; A and D remain unchanged. | No retuning required |
| Character | The six open strings form a complete D major chord with strong root and fifth drones. | Balanced and familiar across most styles |
| Best for | Slide guitar, fingerstyle, folk, blues, songwriting, drones, and one-finger major chords. | General chords, scales, lessons, and repertoire |
After a large tuning change, check string tension, fret buzz, intonation, and whether a different string gauge would suit a permanent setup.
Frequently Asked Questions
What notes are in Open D Tuning?
From the lowest string to the highest, use D2 - A2 - D3 - F#3 - A3 - D4.
How do I change from standard tuning?
From standard, lower both E strings to D, lower B to A, and lower G to F#; A and D remain unchanged.
What is Open D Tuning best for?
Slide guitar, fingerstyle, folk, blues, songwriting, drones, and one-finger major chords.
Do I need different guitar strings?
Occasional moderate retuning usually works with an existing set. Permanent low or high tunings may need a different gauge and a setup for stable tension, action, and intonation.
Should I tune up or down to the target?
Approach the final note from slightly below when possible. This helps the string settle around the tuning-post tension instead of immediately slipping flat.
Can I use the tuner on a phone?
Yes. Open the preset tuner, allow microphone access, keep the phone near the guitar, and play one clear open string at a time.
