Tune to D G D G B D so that strumming all six open strings produces a G major chord. The tuner is ready for Open G as soon as you press Start.
Open G makes slide playing and chordal rhythm parts direct because the open strings already form the home chord. Straight barre shapes can move major chords around the neck, while the repeated D and G notes give riffs and fingerpicked patterns a resonant foundation.
The sixth, fifth, and first strings are lowered from standard tuning. Standard gauges work for many players, although the low D can feel softer than usual. If Open G becomes a permanent setup, a slightly heavier sixth string and a small intonation check may improve consistency.
Lower the sixth string to D2 before tuning the fifth string to G2. Because both low strings move from standard, use the labeled string targets and listen to one string at a time to avoid swapping their intended notes.
The sixth, fourth, and first strings should all be D notes across three octaves. The fifth and third strings should both be G, one octave apart. Once those pairs agree, the B3 on the second string supplies the major third that makes the open strum clearly sound like G major.
Open G is built from the notes of a G major chord: G, B, and D. The lowest note happens to be D rather than G, giving the open chord an inverted bass. Many players avoid the sixth string when they want G itself to be the bass note.
