What the G7 chord sounds like

The dominant seventh sounds tense and wants to move on: the third and the minor seventh form a tritone that pulls towards the tonic. It is also the basic chord of the blues and early rock'n'roll.

Notes of the G7 chord

Degree	Note	Interval from the root
1	G	root
3	B	major third (4 semitones)
5	D	perfect fifth (7 semitones) – often omitted on fretted instruments
7	F	minor seventh (10 semitones)

How to play it – with fingering

Open position

String 1 (e): fret 1, index finger (F4)
String 2 (B): open (B3)
String 3 (G): open (G3)
String 4 (D): open (D3)
String 5 (A): fret 2, middle finger (B2)
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 3, index finger (D4)
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.

Position 3

String 1 (e): fret 3, index finger (G4)
String 2 (B): fret 6, little finger (F4)
String 3 (G): fret 4, middle finger (B3)
String 4 (D): fret 5, ring finger (G3)
String 5 (A): not played
String 6 (E): not played

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 G7 with a capo

A capo clamps all the strings at one fret, so a familiar open shape sounds higher. You can also get a G7 chord with these open shapes:

Capo: fret 3
shape: E7

Capo: fret 5
shape: D7

Capo: fret 7
shape: C7

Frequently asked questions

What notes are in the G7 chord?

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

What is the easiest way to play G7 on guitar?

The easiest shape above is “Open position”, rated easy. We show 6 shapes, from open and easy versions to movable barre shapes higher up the neck. With a capo you can also play it as a E7 shape at fret 3 or a D7 shape at fret 5.

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 G7 shapes?

On a fretted instrument you can't always play every note of a 4-note chord. The fifth (D) may be dropped – the chord keeps its character without it.

How is the G7 chord written?

The chord symbol is G7, and its full name is G dominant seventh.
