Gmaj7 piano chord, G major 7th notes and fingering.

The Gmaj7 piano chord is G major 7th: G, B, D and F#. It is the G major triad with the major seventh (F#) added on top, eleven semitones above the root and a single semitone below the next G. Chord charts write it as Gmaj7, GMaj7 or GM7.

How to play Gmaj7 on piano

1. Find G on the keyboard. G is the white key between the first and second black keys of the group of three.
2. With your right hand, put finger 1 on G, finger 2 on B, finger 3 on D and finger 5 on F#. Finger 1 is the thumb.
3. Press all four keys together. In root position they run from G3 to F#4, a reach of 11 semitones. Play chord sounds them together and Arpeggio sounds them one by one, from the bottom up.
4. Click Left hand to see the left hand. It plays G2 to F#3, one octave lower: G with finger 5, B with finger 3, D with finger 2, F# with finger 1.
5. The cards under the keyboard hold the four positions, with G, B, D and F# at the bottom in turn. Play and Arpeggio on a card play that position.
6. Open Note names. As written the keys read G, B, D and F#. Sharps shows G, B, D and F#, and Flats shows G, B, D and Gb. This chord is written with sharps, so As written and Sharps match.

How Gmaj7 is built

Counted from the root, the formula is 0, 4, 7, 11. Stacked on each other the gaps are 4 + 3 + 4: a major third, a minor third and another major third. The seventh (F#) sits one semitone under the next G, so the top and the root rub together very gently. That small clash gives the chord its soft, spacious sound.

Worked example: the pitch of G3. On a piano tuned to A4 = 440 Hz, a note 14 semitones below A4 has the frequency 440 × 2^(-14/12), which is about 196.00 Hz. B3 is 10 semitones below A4, so 440 × 2^(-10/12) gives about 246.94 Hz.

What the keys look like under your hand

G has a black key on each side, F# on its left and Ab on its right. One of the four notes is a black key (F#) and three are white keys (G, B and D). Your little finger plays F#, a black key with F and G beside it. The little finger is short, so let the hand lean a little toward its edge and aim for the middle of the key.

Gmaj7 inversions and fingering

Gmaj7 has four positions. In root position G is at the bottom. In the first inversion, B is at the bottom and the chord is written Gmaj7/B. In the second inversion, D is at the bottom and the chord is written Gmaj7/D. In the third inversion, F# is at the bottom and the chord is written Gmaj7/F#. The tightest reach, 8 semitones from the lowest key to the highest, is the first inversion and third inversion. The widest, at 11, is the root position.

The keys that hold Gmaj7

Gmaj7 fits four of the major and natural minor keys that have a standard key signature, which means every note of it comes from that key's scale. The simplest is G major, with 1 sharp, where it is chord Imaj7.

Progressions that use Gmaj7, with the chord numbers and the chords in that key:

• G major: Imaj7-V7-vi7-IVmaj7, which is Gmaj7, D7, Em7, Cmaj7, the four-chord loop heard in a great deal of pop.
• E minor: i7-IIImaj7-VII7-iv7, which is Em7, Gmaj7, D7, Am7, a loop that climbs to III and VII.
• D major: Imaj7-IVmaj7-V7-Imaj7, which is Dmaj7, Gmaj7, A7, Dmaj7, the three-chord cadence of folk, rock and blues.

Here is a worked example in G major. The chord before Gmaj7 in the first progression above is Cmaj7 (C, E, G and B). From Cmaj7 in root position, the closest way to reach Gmaj7 is its second inversion (D, F#, G and B, lowest note first): two notes stay where they are, and the others move 4 semitones in total, counting each note against the note in the same place from the bottom.

Look at the top three notes of Gmaj7: B, D and F# make a B minor chord (B, D and F#). A major 7th is a minor triad with the root added underneath.

What Gmaj7 sounds like

Major 7th chords sound soft, warm and a little dreamy. They are at home in jazz, soul, bossa nova, lo-fi and ballads, and they do not need to resolve the way a dominant 7th does, so they can sit at the end of a phrase.

Gmaj7 is the Imaj7 chord in G major, the IIImaj7 chord in E minor and the IVmaj7 chord in D major.

A common mistake with Gmaj7

A common mistake is pressing F instead of F# on top, one semitone lower than the seventh of Gmaj7. That gives G7 (G, B, D and F), a dominant 7th with a tense sound. The top note of Gmaj7 should be the one right below the next G.

Chords to learn next
