Chords in the Key of G: The 7 Chords, Progressions and Songs

If you play guitar, you'll spend a lot of time in the key of G. It's arguably the most guitar-friendly key there is: the main chords are easy open shapes, the open strings ring along with them, and it suits a wide range of singing voices. Folk, country, bluegrass, rock and pop are full of songs in G.

This guide shows the seven chords in the key of G, why they belong together, how to play each one, the progressions you'll use most, and a few variations that make songs in G sound richer.

The 7 chords in the key of G

Every major key has seven chords, one built on each note of its scale. The G major scale is G A B C D E F#, so the chords are:

Number	Chord	Type	Notes
I	G	Major	G B D
ii	Am	Minor	A C E
iii	Bm	Minor	B D F#
IV	C	Major	C E G
V	D	Major	D F# A
vi	Em	Minor	E G B
vii°	F#dim	Diminished	F# A C

Uppercase Roman numerals are major chords; lowercase are minor. This pattern (major, minor, minor, major, major, minor, diminished) is the same in every major key, which is what makes it so useful. Learn it once and you can find the chords in any key. Our guide to the Nashville number system shows how musicians use these numbers to play in any key on the spot.

How to play the chords in G

Five of the seven are easy open chords. Bm is the only one that's usually a barre chord, and it has an easy four-string version.

• G (I): the home chord. Strum all six strings. See the G major chord page.
• Am (ii): strum from the A string. It leads naturally to D.
• Bm (iii): the easy four-string version is shown. The full barre is on our B minor chord page.
• C (IV): strum from the A string.
• D (V): strum the top four strings. D pulls strongly back to G.
• Em (vi): the relative minor of G. They share two notes, G and B.
• F#dim (vii°): rarely used in pop songs. A D/F# slash chord often takes its place.

Why these chords fit together

Every chord in the key is built only from the seven notes of the G major scale. That's why they sound good in almost any order: they share notes. G and Em share two notes, C and Am share two notes, and D contains the F# that makes the whole key "lean" toward G.

Each chord also has a job:

• G (I) feels like home. Songs usually start or end here.
• C (IV) moves away from home, gently.
• D (V) creates tension that wants to resolve back to G.
• Em (vi) adds a sad or reflective color.
• Am (ii) usually leads to D, setting up the return to G.

The most common progressions in G

Progression	Numbers	Where you hear it
G – C – D – G	I – IV – V – I	Folk, country, rock and roll
G – D – Em – C	I – V – vi – IV	Countless modern pop songs
G – Em – C – D	I – vi – IV – V	1950s ballads, "doo-wop"
Em – C – G – D	vi – IV – I – V	Emotional pop and rock
Am – D – G	ii – V – I	Jazz, pop, any song ending
G – Bm – C – D	I – iii – IV – V	Uplifting singer-songwriter

Try each one with four strums per chord. Notice how G – D – Em – C and Em – C – G – D use the same four chords but feel different: one bright, one wistful. Our guide to guitar chord progressions covers twelve essential patterns.

Songs in the key of G

Many traditional songs are commonly played in G, including "Amazing Grace," "Will the Circle Be Unbroken" and "Oh! Susanna." A huge number of modern pop, country and rock songs are also written in G or played in G with a capo. If a song you like uses only G, C, D and Em, it's almost certainly in G. Our list of easy guitar songs for beginners includes many G, C, D songs.

Variations that make G sound richer

Guitarists rarely play just the plain triads in G. These substitutions are common and easy:

• G with four fingers (adding the 3rd fret of the B string): fuller, and it makes the change to Cadd9 effortless.
• Cadd9 instead of C: keep your ring and pinky fingers in place from the four-finger G and just move two fingers down a string. A signature sound of acoustic pop.
• D7 instead of D: a bluesier V chord that pulls even harder back to G.
• Dsus4 → D: add your pinky to the 3rd fret of the high e, then lift it. This little movement decorates countless songs.
• Em7 instead of Em and D/F# between G and Em are also common. See slash chords.

The key of G with a capo

Because G shapes are so comfortable, many guitarists play songs in other keys using G shapes and a capo:

Capo fret	G shapes sound in	G – C – D becomes
1	A flat	Ab – Db – Eb
2	A	A – D – E
3	B flat	Bb – Eb – F
4	B	B – E – F#
5	C	C – F – G

If a song is too low for your voice in G, try a capo on the 2nd or 3rd fret. Our guide on how to transpose guitar chords shows how to move any song to a better key.

The relative minor: E minor

Every major key has a relative minor that uses the same notes. For G major, it's E minor. A song that uses the same chords but centers on Em, starting and ending there, is in E minor. Our guide to chords in the key of E minor explains how that changes the mood, and why B7 often appears.

Practicing the key of G

1. Learn the core four: G, C, D and Em. Practice the changes G ↔ C, G ↔ D and Em ↔ C for a minute each.
2. Play the I – IV – V: four strums each on G, C, D, then back to G. Speed up gradually with a metronome.
3. Add Am and Bm: practice Am – D – G and G – Bm – C – D.
4. Try the variations: swap C for Cadd9 and D for D7 and listen to the difference.
5. Play a song: pick any song in G and play it all the way through, even slowly.

Other keys to explore

Once G feels comfortable, the next easiest keys on guitar are C, D, A and E. Each has its own guide: C, D, A and E. G and D share four chords (G, D, Em and Bm), so D is a natural next step.

Soloing in the key of G

When you're ready to play melodies or solos over songs in G, start with the G major pentatonic scale: G, A, B, D and E. Conveniently, those are exactly the notes of the E minor pentatonic scale, so the familiar E minor pentatonic box in open position (frets 0 to 3), or the same box at the 12th fret, works perfectly over G – C – D – Em. Aim for the note G when a phrase ends on the G chord, and it will sound resolved. Our guide to guitar scales for beginners shows the box shapes.

Common mistakes in the key of G

• Muffled G chord: the A string finger leans on the D string. Arch it so the open D, G and B ring.
• Strumming the low E on C or Am: start those chords on the A string.
• Rushing the G to C change: practice it slowly; it's the most common change in the key. The four-finger G and Cadd9 pair makes it much easier.
• Avoiding Bm forever: use the easy four-string version or Bm7 so you can play every song in the key.
