The short version
- Gaug is G augmented. Its notes are G, B and D♯ (formula 1 – 3 – ♯5).
- Easiest way to play it: the open shape, frets 3 2 1 0 0 3 from low E to high E (x = don’t play).
- It sounds unsettled, dreamy, about-to-happen. Use it for one beat between the I chord and the IV or vi chord. It makes the change slide instead of step.
- Gaug isn’t in any major or natural-minor key on its own. It’s a borrowed chord: you drop it in for colour or as a passing chord.
- Try it in: G – Gaug – C – Cm, a chromatic slide straight out of a 1960s ballad.
How to play Gaug 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 4th (D) 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.
- Put your little finger on fret 3 of the 1st (high E) string.
- Let the 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 movable shape, root on the 6th string (3rd fret): 3 x 5 4 4 x. Shape 3 is the movable shape, root on the 5th string (10th fret): x 10 13 12 12 x. 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.
