Open G7 Guitar Tuning
Open G7 sets the six strings from low to high to D G D F B D. Its raw, unresolved and earthy voice works especially well for G blues, bottleneck slide and dominant riffs.

What changes in Open G7
The open chord contains G, B, D and F, creating G7 with D in the bass.
Make the tuning sound intentional
Slide between open G7 and a partial C7 at fret five, then return without stopping the beat.
Shape tip: Resolve the F to E for a major-sixth sound or move it to F-sharp for a major-seven colour.
Retune to D G D F B D safely
Several strings lower from standard; a normal or medium set usually works.
Change one string at a time, approach the target pitch gradually and recheck every string after the neck settles. Stop if a string feels unusually tight, the bridge lifts or the instrument reacts unpredictably.
