Where the fingers go

1
middle finger, thick E string, fret 3
The thickest string, nearest the ceiling.
2
index finger, A string, fret 2
Count from the thick string: E A.
3
ring finger, thin e string, fret 3
The thinnest string, nearest the floor.
4
Leave the D, G, B strings open
They ring without any finger. They are part of the chord.
5
Strum 6 strings, from the thick E string down
All six strings belong to this chord.

The same shape seen along the neck, thin e on top. Numbers are fingers; 0 is an open string.

The notes in G

A chord is three or four notes played together. G major is built from these:

Note	Job in the chord	Where it is in this shape
G	root	thick E string, fret 3; G string, open; thin e string, fret 3
B	major third	A string, fret 2; B string, open
D	fifth	D string, open

The root, G, is the note it is named after. The second note decides the mood: a major third sounds bright, a minor third sounds sad. This chord sounds bright and settled.

Where it sits on the circle of fifths

The circle of fifths lines up the twelve keys so that neighbours share the most notes. Chords next to each other on the circle sound good one after the other, which is why songs move between them.

C and D are G’s neighbours. Most songs in G use one or both.
Em is its relative minor: the same notes, a different home. Swapping between them changes the mood without changing your hand much.

The mistake everyone makes

Watch out

The ring finger mutes the B string

On the thin e string at fret 3, it can lean over. Curl it so the B string rings open.

Tip

Anchor the ring finger

When changing between G and C, the ring finger moves last. Let it be the pivot.

Songs that use it

The partner of C and D. Ode to Joy, Greensleeves, and most campfire songs use it.

In those songs, G is followed by C D7 Am . Practise those changes first.
