The Gmaj7 guitar chord is a major 7th chord with the notes G, B, D, F#. Its first guitar voicing is the open position: low E string at fret 3 (ring finger); A string at fret 2 (index finger); D string open; G string open; B string open; high e string at fret 2 (middle finger). Whether you are learning it for the first time or checking a voicing, this page has the notes, the guitar fingerings, the inversions and alternatives, and the progressions it appears in.
What notes are in the Gmaj7 chord?
The Gmaj7 chord is a major 7th chord, and its notes are fixed: G, B, D, F#. Every voicing on every instrument uses these same notes, in some order and in some octave — change one of them and you are playing a different chord. The table below lists each note with its interval from the root G, so you can see the structure of Gmaj7 at a glance. On the guitar, start with the first voicing above and listen for the notes G, B, D, F# in Gmaj7.
| Note | Interval |
|---|---|
| G | Root |
| B | 3 |
| D | 5 |
| F# | 7 |
The root is G, the note the chord is named after and the note your ear hears as home. Above it, the intervals in Gmaj7 are 3, 5, 7. Learn those intervals rather than memorising the shape alone, because the same interval pattern transposed to another root gives you the same quality of chord anywhere. On the guitar, the notes appear in the order the fingering dictates, but the set of notes never changes.
Gmaj7 sounds mellow and spacious, a tonic colour that feels settled yet richer than a plain major triad. The colour is strongest when all the notes ring clearly. A muted chord tone, especially the 3rd or the 7th where the chord has one, flattens the character of Gmaj7 noticeably. On the guitar, the open position of Gmaj7 puts those notes under your fingers in the order the fingering lists them.
Comparing Gmaj7 with its closest relatives helps to fix it in your ear. In short, major 7th against dominant 7th: Gmaj7 keeps the major 7th F#, while the dominant version flattens it to F. The major 7th sounds dreamy; the dominant 7th sounds restless. Practise the two chords back to back and listen to the one note that changes — that single note is the difference between the two chords. On the guitar, start with the first voicing above and listen for the notes G, B, D, F# in Gmaj7.
How to play Gmaj7 on guitar
On the guitar, Gmaj7 has 3 voicings in the data below, and each one uses the same notes — G, B, D, F# — in a different place on the neck. The first voicing below is the one to learn first, and the alternatives cover the rest of the neck. Finger numbers below use 1 for the index finger, 2 for the middle finger, 3 for the ring finger and 4 for the little finger, and x means the string is not played.
Another way to play Gmaj7 is the open position, in around fret 1: low E string at fret 3 (ring finger); A string at fret 2 (index finger); D string open; G string open; B string open; high e string at fret 2 (middle finger). This voicing is comfortable because the fretted notes sit close together, from fret 2 to fret 3, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in Gmaj7 — G, B, D, F# — sounds, with no buzz and no accidental open string.
Another way to play Gmaj7 is the barre chord, in around fret 1: low E string at fret 2 (index finger); A string at fret 2 (index finger); D string open; G string open; B string open; high e string at fret 2 (index finger). It barres across strings 1 to 2 at fret 2 with the index finger. The barre is the hard part: the index finger must press every string from 1 to 2 evenly at fret 2, so roll it slightly onto its bony side and keep it close to the fret wire. If the barre buzzes, move it a fraction closer to the fret and press from the arm, not the thumb alone. Strum or pluck it slowly first and check that every note in Gmaj7 — G, B, D, F# — sounds, with no buzz and no accidental open string.
The movable voicing is the voicing to learn if you want Gmaj7 in around fret 2: low E string at fret 3 (middle finger); A string at fret 5 (ring finger); D string open; G string open; B string open; high e string at fret 2 (index finger). The stretch is the challenge: the fretted notes span from fret 2 to fret 5, so keep your thumb low behind the neck and let your fingers reach rather than squeezing the neck. Strum or pluck it slowly first and check that every note in Gmaj7 — G, B, D, F# — sounds, with no buzz and no accidental open string.
Choosing between the voicings of Gmaj7 is a musical decision, not a right-or-wrong one. The open or low-position voicing rings the most and suits strumming, while a barre or movable voicing lets you slide Gmaj7 up the neck to any key without changing the shape. When you change chords, pick the voicing of Gmaj7 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into Gmaj7 from the chord that comes before it in your song, not the chord on its own, because the move is the skill. On the guitar, the open position voicing is the place to hear it in Gmaj7.
A short practice routine for Gmaj7 on the guitar: play the first voicing four times slowly, checking each note, then change to it from the chord a fourth above G and back, four times, at a slow tempo. Then play the second voicing the same way. If a note buzzes, stop and fix the finger placement rather than playing through the buzz — clean notes at a slow tempo become clean notes at full tempo, while buzzes practised fast become habits. Use the Guitar Chord Finder to see the diagram for Gmaj7 while you practise, and the Chord Finder to compare it with the same chord on other instruments.
Common mistakes
These are the mistakes that most often make Gmaj7 sound wrong on the guitar, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Clashing the 7th against the root. The major 7th is a semitone below the root, so voicings that put them next to each other in the same octave can sound harsh. Spread the notes out across octaves. On the guitar, the open position of Gmaj7 puts those notes under your fingers in the order the fingering lists them.
Playing it like a plain triad. Leaving F# out turns this into an ordinary major chord and loses the whole point of the maj7 colour. Make the 7th audible. On the guitar, the open position of Gmaj7 puts those notes under your fingers in the order the fingering lists them.
Using it as a dominant. Gmaj7 does not pull to a tonic the way a dominant 7th does. If you need a V chord, use the dominant 7th instead. On the guitar, the open position of Gmaj7 puts those notes under your fingers in the order the fingering lists them.
Barre collapsing on the high strings. In a barre voicing of Gmaj7, the high strings are the ones that buzz first, because the index finger presses hardest near the thumb. If the top notes of Gmaj7 sound dead, roll the barring finger slightly toward the fret and press from the arm, not from squeezing the neck. On the guitar, the open position voicing is the place to hear it in Gmaj7.
Where Gmaj7 is used
Gmaj7 is not a diatonic triad in any major or minor key, because it is an extended or altered chord, but its base triad belongs to the key of C major, the key of D major, the key of G major. a chord for slow, open voicings — it rewards space and light touch. As a dominant-type chord it also points toward C major, the key a perfect fourth above G, which is the tonic it most often resolves to. That is where Gmaj7 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the guitar, the open position of Gmaj7 puts those notes under your fingers in the order the fingering lists them.
Because Gmaj7 is an extended or altered chord, it appears in progressions as a colour or a dominant rather than as a diatonic staple. Try it in place of the plain G triad in a progression you already know, and listen to how the extra notes change the feel — that substitution is the usual way extended chords enter real music. The Chord Progression Builder lets you try Gmaj7 in a progression in any key and hear how it connects to the chords around it. On the guitar, the open position voicing is the place to hear it in Gmaj7.
The same chord on other instruments is covered in Gmaj7 on piano, Gmaj7 on ukulele, Gmaj7 on bass, and the scales that fit over it are the G major scale and the G minor pentatonic scale. Learning Gmaj7 on the guitar and then checking it on another instrument is one of the best ways to fix the notes — G, B, D, F# — in your memory, because the notes stay the same while everything else changes.
Practising Gmaj7
A short worked example makes Gmaj7 concrete. Play the four-chord progression C – G – Am – F in C major, the key Gmaj7 most often resolves toward: C – G – Am – F. Play each chord for one bar at a slow tempo, and listen to how Gmaj7 sounds in that sequence — whether it feels like home, like a lift, or like a chord on its way somewhere else. Then play the same four chords in a different order, starting on Gmaj7 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the guitar, the open position voicing is the place to hear it in Gmaj7.
For a second exercise, play Gmaj7 and then the chord a fourth above G, back and forth, four times each. That move — a chord and the chord a fourth above it — is the most common resolution in Western music, and it is the move Gmaj7 is built for when it acts as a dominant. Finish by playing Gmaj7 on its own, slowly, and naming each note out loud as you play it: G, B, D, F#. Naming the notes while you play them is what turns a shape into knowledge you can use in any key. Test yourself with the Practice Chord Quiz and keep time with the Metronome as the tempo rises. On the guitar, start with the first voicing above and listen for the notes G, B, D, F# in Gmaj7.
Frequently asked questions
Is Gmaj7 hard to play on the guitar?
It depends on the voicing. The first voicing of Gmaj7 on the guitar is the easiest starting point, and the movable voicings further up the neck are harder because they need a barre or a wider stretch. Practise the first voicing cleanly at a slow tempo before you try the others, and the harder shapes will come more easily.
What is the easiest voicing of Gmaj7 on the guitar?
The open position is the easiest voicing listed for Gmaj7 on the guitar: frets 3–2–0–0–0–2, fingers 3–1–0–0–0–2. Learn that shape first, get every note ringing cleanly, and only then move on to the alternative voicings further up the neck.
Is Gmaj7 a major chord?
Yes — Gmaj7 is a major 7th chord, built on a major triad (G, B, D) with the major 7th F# added. It sounds major, but with a dreamy, jazzy colour the plain triad does not have. On the guitar, check the first voicing above for that note.
What is the difference between Gmaj7 and G7?
Gmaj7 uses the major 7th F#; G7 uses the flattened 7th F. Gmaj7 sounds settled and shimmering, G7 sounds bluesy and wants to resolve. On the guitar, check the first voicing above for that note.
Where is Gmaj7 used?
Gmaj7 is most at home as a tonic chord in jazz, bossa nova and soft pop, and as the IV chord in major keys. It suits slow tempos and open voicings where its shimmer has room to breathe. On the guitar, check the first voicing above for that note.
