What the G13 chord sounds like

A thirteenth chord is a dominant seventh with an added major thirteenth (the sixth an octave up). On an instrument the fifth and often the ninth are dropped, and the eleventh is left out. A classic jazz and blues dominant.

How to play it – with fingering

Easy version

String 1 (e): open (E4)
String 2 (B): open (B3)
String 3 (G): open (G3)
String 4 (D): fret 3, middle finger (F3)
String 5 (A): open (A2)
String 6 (E): fret 3, index finger (G2)

Open position

String 1 (e): fret 1, index finger (F4)
String 2 (B): open (B3)
String 3 (G): open (G3)
String 4 (D): fret 2, middle finger (E3)
String 5 (A): open (A2)
String 6 (E): fret 3, ring finger (G2)

E shape, fret 3, barre at fret 3

String 1 (e): fret 3, index finger (G4)
String 2 (B): fret 5, little finger (E4)
String 3 (G): fret 4, middle finger (B3)
String 4 (D): fret 3, index finger (F3)
String 5 (A): fret 5, ring finger (D3)
String 6 (E): fret 3, index finger (G2)

For the barre, lay your index finger flat across all the marked strings at fret 3; your other fingers press the higher frets.

The “C, A, G, E and D shapes” are the CAGED system: you slide the shape of the open C, A, G, E or D chord up the neck and your index finger (a barre) takes over the job of the nut. That way the same chord can be played in five places, anywhere on the fretboard.

Tuning: E A D G B E (low to high). String 6 is the thickest, the low E. In the diagram, × means the string is not played, and a circle means an open string.

Playing G13 with a capo

A capo clamps all the strings at one fret, so a familiar open shape sounds higher. You can also get a G13 chord with these open shapes:

Capo: fret 3
shape: E13

Frequently asked questions

What notes are in the G13 chord?

G, B, D, F, A, E. The root is G; the intervals of the other notes from the root: major third, perfect fifth, minor seventh, major second, major sixth.

What is the easiest way to play G13 on guitar?

The easiest shape above is “Easy version”, rated easy. We show 5 shapes, from open and easy versions to movable barre shapes higher up the neck. With a capo you can also play it as a E13 shape at fret 3.

How do I read the chord diagram?

Strings run from the lowest (left) to the highest (right) – tick “Left-handed” to mirror it. Rows are frets; a number at the side shows the starting fret. Dots are fingers (1 index, 2 middle, 3 ring, 4 little), a long bar is a barre, × means don't play that string and ○ means play it open.

Why is a note missing from some G13 shapes?

On a fretted instrument you can't always play every note of a 6-note chord. The fifth (D) and ninth (A) may be dropped – the chord keeps its character without them.

How is the G13 chord written?

The chord symbol is G13, and its full name is G thirteenth.
