G Major Seventh Piano Chord (Gmaj7)

Gmaj7 is built from G, B, D and F# — the formula 1 · 3 · 5 · 7, or 4, 7 and 11 semitones above G. The shape uses 3 white and 1 black key, and you can hear it, invert it and compare it below.

Chord tones

The notes in Gmaj7

A major seventh chord places the seventh degree of the major scale on top of a major triad, one semitone below the octave. That narrow interval rubs gently against the root and produces the soft, hazy quality heard throughout jazz, soul and slow ballads. It is the natural seventh chord on the first and fourth degrees of a major scale.

Step by step

How to play Gmaj7 on piano

Find G: it is the white key between the first and second black keys of a group of three.
Build upwards from G using 4, 7 and 11 semitones to reach B, D and F#.
With the right hand, place finger 1 on G, finger 2 on B, finger 3 on D and finger 5 on F#. Keep the wrist level and the knuckles rounded.
Move your hand a little further in towards the fallboard so the black key sits comfortably under your fingers.
Play the notes together, then one at a time from the bottom up, and listen to how Gmaj7 settles.
Try first inversion as well: B – D – F# – G. Inversions let you change chords without jumping around the keyboard.

Inversions

Gmaj7 in 4 positions

An inversion keeps the same 4 notes and simply moves the lowest one up an octave. Learning them means you can change chords with small hand movements instead of jumping to a new part of the keyboard.

Root position

G – B – D – F#

The root G is the lowest note. This is the shape most people learn first.

First inversion

B – D – F# – G

B is the lowest note, so the major third sits in the bass and the notes below it move up an octave.

Second inversion

D – F# – G – B

D is the lowest note, so the perfect fifth sits in the bass and the notes below it move up an octave.

Third inversion

F# – G – B – D

F# is the lowest note, so the major seventh sits in the bass and the notes below it move up an octave.

In context

Which keys contain Gmaj7

In D major the chord functions as IVmaj7. Altogether it is produced by the scales of 4 keys, so learning it once pays off in several places.

D majorIVmaj7
G majorImaj7
E minorIIImaj7
B minorVImaj7

Chord tones are spelled by the degree they occupy, so the third of a minor chord is written as a flat rather than a sharp even though it is the same key on the piano. A double sharp such as F## means the key one whole tone above F.

Compare

Gmaj7 against G7

Gmaj7 and G7 share G, B and D. Moving the minor seventh F up 1 semitone to the major seventh F# turns G7 into Gmaj7.

Practise the pair together: hold the shared notes G, B, D still and move only the one finger. Hearing that single change is the quickest way to recognise the two chords by ear.
