Gm6 Chord on Guitar
Gm6 = G – A# – D – E (Root, Minor 3rd, Perfect 5th, Major 6th)
Gm6 raises the fifth of the G minor barre by two frets to the major sixth, the same small physical move that turns F# minor into F#m6 one fret down — but the emotional shift it produces is disproportionate to how little actually changes in the hand.
G-Bb-E: root, minor third, and major sixth, with the fifth dropped from this compact voicing and the root doubled. Pairing a minor third with a major sixth is the defining interval combination of the Dorian mode, giving Gm6 that same restless, cinematic quality associated with film-score minor passages and modal jazz rather than a straightforwardly sad minor triad. It works as a more harmonically active substitute for plain G minor, particularly effective right before a cadence into D major or D7, where the extra motion toward the dominant pays off.

How to Practice It
From the G minor barre, move the finger holding the fifth up two frets to the sixth, and make sure that new note actually rings rather than getting muted in the process, since the fifth disappears from this voicing entirely rather than being doubled elsewhere. Practice resolving Gm6 into Gm and then into D7, since hearing the sixth's pull toward that dominant is what makes the color chord's purpose click rather than it just sounding like an unusual variant of G minor.
Common Progressions
- Gm – Gm6 – D7 – Gm (i – i6 – V7 – i in G minor, a classic minor cadential move)
- Gm6 – C – Gm6 (a static Dorian-flavored vamp)
- Eb – Gm6 – F (a color substitution for Gm within Bb major-adjacent material)
- Gm6 – F – Eb – D7 (a descending minor-key turnaround)
FAQ
- What note does Gm6 change relative to plain G minor?
- The fifth (D) is replaced by the major sixth (E), so the fifth drops out of this particular voicing entirely while the sixth becomes the new color tone.
- Why is Gm6 described as sounding Dorian?
- The Dorian mode pairs a minor third with a major sixth, exactly the two color intervals present in an m6 chord, giving it that mode's characteristic moody-but-not-fully-dark quality.
- Is Gm6 much harder to fret than G minor?
- Not really — one finger moves two frets further than it would for the plain minor triad, with no additional fingers required.
- When is Gm6 a better choice than plain Gm?
- When a minor progression wants extra harmonic motion or a moodier edge, especially right before a dominant chord, since the added sixth points toward that resolution more strongly than a plain minor triad does.
- Does Gm6 share notes with a chord built on a different root?
- Yes — its four notes are identical to a half-diminished (m7b5) chord built a major sixth higher, since both are the same four pitches viewed from different roots, even though the two chords function quite differently.
