The standard grips this chord is usually shown with.
G13 is G, B, D, F, A and E — G9 with the thirteenth added on top.
It sounds big and open. Six notes will not fit under four fingers: the fifth goes first, then the ninth, and the third, flat seventh and thirteenth stay.

| G | B | D | F | A | E |
|---|---|---|---|---|---|
| 1 | 3 | 5 | ♭7 | 9 | 13 |
Dominant — the full V chord.
Also written Gdom13 or G dominant 13. The same chord either way; which spelling you meet depends on who wrote the chart.
G13 in 2nd inversion puts D in the bass instead of G, the 5th of the chord. The notes are the same; what changes is what the bass line does, which is most of why you would reach for it — it lets the lowest voice move by step where the root would have jumped.
One of G13’s 8 common shapes does this: 10-10-10-10-12-12.
Start with 302001 — no barre and 3 open strings. 1 of the 8 shapes here sits in open position. 6 of the 8 need a barre. Together they cover the neck from the 1st fret to the 15th.

The same notes rebuilt from scratch give 2 shell, 14 drop 2, 9 drop 3, 24 rootless and 6 open string voicings, each on its own page.
Tensions. A shell of G13, root, third and seventh, leaves a string free, and the tones that belong over it are the #11 (C#).
G13 is the V of C, and that is where it goes if it goes anywhere: the third and the flat seventh are a tritone apart, and both resolve by a semitone into C.
Voice by voice, G13 → C. 2 voices move by a semitone, and 2 notes are common to both chords.
| In G13 | Moves | In C |
|---|---|---|
| G, the root | stays where it is | G, the fifth |
| B, the major third | rises a semitone | C, the root |
| D, the fifth | falls a whole tone | C, the root |
| F, the flat seventh | falls a semitone | E, the major third |
| A, the ninth | falls a whole tone | G, the fifth |
| E, the thirteenth | stays where it is | E, the major third |
