The short version
- G7 is G seventh. Its notes are G, B, D and F (formula 1 – 3 – 5 – ♭7).
- Easiest way to play it: the open shape, frets 3 2 0 0 0 1 from low E to high E (x = don’t play).
- It sounds bluesy, restless, waiting to resolve. Use it as the V7 that pulls a song home, or play every chord as a 7th and congratulations, you’re in a 12-bar blues.
- G7 turns up in 2 keys: C major (as the V7) and A minor (as the VII7).
- Try it in: G7 – C7 – G7 – D7, the bones of a 12-bar blues.
How to play G7 on guitar, step by step
Start with the shape marked “Start here” above: the open chord, the easiest way in.
- Put your index finger on fret 1 of the 1st (high E) string.
- Put your middle finger on fret 2 of the 5th (A) string.
- Put your ring finger on fret 3 of the 6th (low E) string.
- Let the D, G and B strings ring open.
- Strum from the 6th (low E) string down, then press Strum on this page to check it sounds the same.
Once that’s comfy, try the other 2 shapes. Shape 2 is the barre chord, root on the 6th string (3rd fret): 3 5 3 4 3 3. Shape 3 is the barre chord, root on the 5th string (10th fret): x 10 12 10 12 10. Same chord, different spot on the neck, which helps when the next chord lives nearby.
Buzzing? Press just behind the fret wire, not in the middle of the fret, and come down on your fingertips so they don’t touch the next string. Then press Strum and play along: if yours sounds duller, one string is muted somewhere.
