G Dominant 7th Guitar Chord (G7)

G dominant 7th is a four-note chord built from G (the root), B (the major third), D (the perfect fifth), and F (the minor seventh). It has that gritty, unresolved dominant-seventh bite. In a 12-bar blues in G it can sit on the tension all night; in other keys it is the V7 chord pushing hard toward home. Below are 4 ways to play it in standard tuning, easiest shape first.

How to play it

Place your index finger on the high E (1st) string at fret 1, your middle finger on the A (5th) string at fret 2, and your ring finger on the low E (6th) string at fret 3. Let the D (4th), G (3rd), and B (2nd) strings ring open. Strum all six strings.

Once that shape is comfortable, try the other 3 voicings above — same notes, different neck positions and textures.
