THE TUNEGUITAR GUIDE
Understand DADGAD
Why the open strings do not choose major or minor
DADGAD contains D, A and G, but neither F nor F sharp. Those missing thirds are what keep the open sound from declaring a D-minor or D-major chord. The G adds a suspended fourth. Let the low D ring and alternate a fretted F with F sharp on another string to hear how one added note changes the harmony.
Keep the middle of the guitar still
From standard, strings 5, 4 and 3 stay A2, D3 and G3. Lower strings 6, 2 and 1 by two semitones each. The second string becomes A3, an octave above the fifth string A2; the highest D4 is an octave above the fourth string D3. Those two octave pairs provide independent checks after the microphone pass.
The one-string route to Open D
DADGAD and Open D differ at string 3 only. Lower G3 to F sharp3 for Open D major, or to F3 for Open D minor. Do not lower the second string again: it is already A in all three tunings. Saving each setup with its full name makes these closely related sounds easier to switch between without losing track of the third string.
Your string-by-string route from standard
This is a comparison of target pitches, not a recommendation to use every tuning on every guitar. Start from the tuning your instrument actually has. Use the directions and the octave labels together.
| String | Start | Target | Adjustment |
|---|---|---|---|
| 6 | E2 | D2 | Lower 2 semitones |
| 5 | A2 | A2 | Keep this target |
| 4 | D3 | D3 | Keep this target |
| 3 | G3 | G3 | Keep this target |
| 2 | B3 | A3 | Lower 2 semitones |
| 1 | E4 | D4 | Lower 2 semitones |
Nearby tunings, compared by their actual notes
These are the three closest six-string presets by total semitone movement from this setup. The ranking describes target changes, not playing difficulty or physical suitability. A familiar name can hide a different middle-string layout.
| Next tuning | All target notes | Strings that change |
|---|---|---|
| Open D | D2 · A2 · D3 · F♯3 · A3 · D4 | 3 |
| Open D minor | D2 · A2 · D3 · F3 · A3 · D4 | 3 |
| Drop D | D2 · A2 · D3 · G3 · B3 · E4 | 2, 1 |
