Open G (GDGB) Tuning
Tune your violin to Open G (GDGB) — G3, D4, G4, B4
About Open G (GDGB) Tuning
Open G tuning (G3-D4-G4-B4) produces a G major chord when all four strings are played open. The A string is lowered from A4 to G4, and the E string is lowered from E5 to B4. This transforms the violin into a natural accompaniment instrument where simple barre techniques produce full chords.
Open G is deeply rooted in American fiddle traditions, particularly old-time Appalachian music and Southern string band repertoire. Fiddlers in these traditions often used open tunings to create a droning, modal sound that complements banjo and guitar in ensemble playing. The open G chord provides a constant harmonic foundation while the bow plays melody on the upper strings.
In Open G, playing in the key of G becomes effortless — you have a built-in drone and chord. The tuning also makes double stops and triple stops more accessible, since more useful intervals fall under the fingers naturally. However, music written for standard tuning won't translate directly — fingering patterns and positions all change.
String Notes
Recommended Strings
Since both the A and E strings are tuned down (A→G, E→B), string tension decreases noticeably. Standard medium-tension strings generally work fine for Open G — the reduced tension actually makes the instrument easier to play and gives a slightly mellower tone that suits folk styles. If strings feel too loose, consider a slightly heavier gauge for the top two strings.
How to Tune to Open G (GDGB)
- 1.Start from standard GDAE tuning. Two strings need to change: the A string and the E string.
- 2.Lower the A string (2nd string) from A4 down to G4. Play it against the open G string — it should sound exactly one octave higher than the G3.
- 3.Lower the E string (1st string, thinnest) from E5 down to B4. This is a significant drop — lower it carefully.
- 4.Verify by playing all four strings open. You should hear a clear G major chord: G3-D4-G4-B4.
- 5.Check the intervals: G to D is a perfect fifth, D to G is a perfect fourth, and G to B is a major third. If any interval sounds off, retune that string.
Best Keys for Open G (GDGB)
G Major
The home key — all open strings form a G chord. Melodies in G major flow naturally over the open-string drone.
D Major
Bar all strings at a position that yields D-A-D-F#. The dominant key works well with the open G as a IV chord.
C Major
Accessible through first-position fingering. The open G and D strings serve as chord tones in C major harmony.
E Minor
The relative minor of G. Open strings provide a natural drone that gives E minor melodies a haunting quality.
