G Major Triads on Guitar: Every Inversion on Every String Set

The notes of G
G major is a major third (four frets) with a minor third (three frets) on top. Root position puts G at the bottom (G, B and D); first inversion puts B at the bottom (B, D and G); second inversion puts D at the bottom (D, G and B).
G on every string set
On the low E, A and D strings: root position at frets 0–3, first inversion at frets 5–7 and second inversion at frets 9–10.
On the A, D and G strings: root position at frets 7–10, first inversion at frets 0–2 and second inversion at frets 4–5.
On the D, G and B strings: root position at frets 3–5, first inversion at frets 7–9 and second inversion at fret 0.
On the G, B and high e strings: root position at frets 0–10, first inversion at frets 3–4 and second inversion at frets 7–8.
Where the inversions sit in the CAGED shapes
The practice pad above shows G's triads inside each CAGED shape. Use the R, 2, 3 and V switches to see each arrangement:
- Root position: C shape (fret 7), A shape (fret 10), G shape (fret 12) and E shape (fret 3).
- First inversion: C shape (fret 7), G shape (fret 12) and E shape (fret 3).
- Second inversion: C shape (fret 7), A shape (fret 12) and E shape (fret 4).
Where G appears
G belongs to 8 keys: V in C major, IV in D major and I in G major; III in E minor, VII in A minor and VI in B minor; V in C harmonic minor and VI in B harmonic minor.
Of those, C major, D major, G major, E minor and A minor are keys guitarists play in constantly, because their open strings ring with the scale, so G turns up often in songs.
Open strings and capo options for G
Three open strings are part of G: the D string (the fifth), the G string (root) and the B string (the third). Because the root is among them, you can let it drone under any of the shapes.
There's an open G chord at the nut: the G shape.
With a capo you can also play it as the E shape with the capo at fret 3, the D shape with the capo at fret 5 and the C shape with the capo at fret 7.
