Chords in the Key of G Major

What are the chords in G major?

Take the G major scale — G A B C D E F# — and build a chord on each note by stacking every other scale note on top of it. Those seven chords are the chords in the key:

• G — I, major, built on G
• Am — ii, minor, built on A
• Bm — iii, minor, built on B
• C — IV, major, built on C
• D — V, major, built on D
• Em — vi, minor, built on E
• F#dim — vii°, diminished, built on F#

The pattern of qualities is the same in every major key — only the letters change. Learn the numerals and you can find the chords of any key in seconds.

Which chords to play first

G, C and D — the I, IV and V — carry most songs in G major. Add Em (the vi, the relative minor) and you have the four chords behind a large share of popular music.

• Pop Anthem — 1–5–6m–4 — G – D – Em – C. Heard in Let It Be (verse), Don't Stop Believin'.
• Rock / Country / Blues Backbone — 1–4–5 — G – C – D. Heard in Wild Thing, Twist and Shout.
• 50s / Doo-Wop — 1–6m–4–5 — G – Em – C – D. Heard in Stand By Me, Earth Angel.
• Rhythm Changes Turnaround — 1–6m–2m–5 — G – Em – Am – D. Heard in I Got Rhythm, Heart and Soul (original).

The same chords as 7ths

Stack one more third on each and you get the seventh chords of G major: Gmaj7, Am7, Bm7, Cmaj7, D7, Em7, F#m7♭5. Same roots, same function, a jazz and soul colour. The V as a dominant seventh (D7) is the one that pulls hardest back to G.

G major and E minor share every chord

E minor uses the same seven notes as G major, so it has the same seven chords — the relative minor. What changes is which chord is home: G in G major, Em in E minor. A song can drift between the two without changing a single chord shape.

How to practice the chords of G major

1. Play G – C – D – G slowly, one strum per chord, until the changes are clean.
2. Open the chord builder in this key and turn on Smooth Voice Leading — it re-fingers each change so your hand barely moves.
3. Then play the scale over the chords. Every note of G major fits every chord above, which is why the scale and the key are the same thing seen from two sides.
