G6 Chord on Guitar
G6 = G – B – D – E (Root, Major 3rd, Perfect 5th, Major 6th)
A chord is the same notes however you stack them, and which one sits at the bottom changes how it sounds. The chord builder puts each of G6's notes in the bass in turn, names the result, and plays it.
Hear every inversion of G6 →G6 lives one fret above the F#6 barre, at the third fret, and is built the identical way — the note that would normally hold the fifth in a G major barre slides two frets higher to become the major sixth instead. The physical motion transfers directly from the F#6 shape a fret below, which makes G6 a quick add to a player's vocabulary once F#6 is already known.
G-B-D-E: root, major third, fifth's replacement (the sixth), doubled root. As with any major-sixth chord, this reads as a brighter, jazzier cousin of the plain major triad, associated with swing-era big-band endings and the kind of dance-hall harmony that predates the modern habit of ending progressions on a seventh chord. In G major it's a tonic color substitute; it also turns up as IV6 in D major, giving that key's subdominant an extra lift without changing its basic function.

How to Practice It
Learn the plain G major barre at the third fret first if it isn't already automatic, then practice sliding just the finger on the D string up two frets to the sixth. Since this is the same relationship as F#-to-F#6 one fret down, use the two chords together as a pattern-recognition exercise — moving between roots while keeping the same internal finger movement is exactly the skill that makes movable barre shapes worth learning in the first place.
Common Progressions
- G6 – C – G6 (I6 – IV – I6 in G major, a swing-style tonic loop)
- D – G6 – Em (V – I6 – vi in G major)
- G6 – C6 – D7 (parallel sixth-chord motion into a dominant resolution)
- Em – G6 – C – D (vi – I6 – IV – V, using the sixth as a brighter tonic color)
FAQ
- What changes between G major and G6?
- The D-string note moves from the fifth (D) up two frets to the major sixth (E), while every other string in the third-fret barre stays exactly where it is.
- Is G6 the same shape as F#6 just moved up a fret?
- Yes — it's the identical movable E-shape pattern with the sixth substituted for the fifth, simply slid one fret higher to change the root from F# to G.
- Why does G6 sound like swing or big-band music?
- Major-sixth chords were the standard tonic-ending color in dance-band and swing arrangements before seventh-chord tonics became the more common modern default, so the sound is strongly associated with that earlier harmonic vocabulary.
- Does G6 work as a substitute for G major in a chord chart?
- Usually yes, since it keeps the root and third intact and simply brightens the color by swapping the fifth for a sixth, which rarely conflicts with a melody or other harmony written for the plain triad.
- Is G6 harder to play than plain G major?
- No — it's the same barre with one finger repositioned two frets higher, so the physical demand is essentially identical to the plain major chord.
