The Gm6 mandolin chord is built from the notes G, A#, D, E. Its first mandolin voicing is the open position: G string open; D string open; A string at fret 1 (index finger); E string open. It is a minor 6th chord, and this page gives you its exact notes, the fingerings that work on the mandolin, the mistakes to avoid and the progressions it appears in.
What notes are in the Gm6 chord?
The Gm6 chord is a minor 6th chord, and its notes are fixed: G, A#, D, E. 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 Gm6 at a glance. On the mandolin, start with the first voicing above and listen for the notes G, A#, D, E in Gm6.
| Note | Interval |
|---|---|
| G | Root |
| A# | b3 |
| D | 5 |
| E | 6 |
The root is G, the note the chord is named after and the note your ear hears as home. Above it, the intervals in Gm6 are b3, 5, 6. That combination is what makes Gm6 sound the way it does: the intervals decide the colour, and the root decides the pitch. On the mandolin, the notes appear in the order the fingering dictates, but the set of notes never changes.
Gm6 sounds moody and sophisticated, with the added 6th ({sixth}) giving the minor triad a bittersweet lift. 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 Gm6 noticeably. On the mandolin, start with the first voicing above and listen for the notes G, A#, D, E in Gm6.
Comparing Gm6 with its closest relatives helps to fix it in your ear. In short, minor 6th against minor 7th: Gm6 adds the 6th E; the minor 7th adds the flattened 7th F instead. The 6th sounds more elegant and more tense. 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 mandolin, start with the first voicing above and listen for the notes G, A#, D, E in Gm6.
How to play Gm6 on mandolin
On the mandolin, Gm6 has 3 voicings in the data below, and each one uses the same notes — G, A#, D, E — 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.
The open position puts Gm6 in open position: G string open; D string open; A string at fret 1 (index finger); E string open. This voicing is comfortable because the fretted notes sit close together, from fret 1 to fret 1, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in Gm6 — G, A#, D, E — sounds, with no buzz and no accidental open string.
The movable voicing is the voicing to learn if you want Gm6 in around fret 5: G string open; D string at fret 8 (middle finger); A string at fret 5 (index finger); E string open. The stretch is the challenge: the fretted notes span from fret 5 to fret 8, 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 Gm6 — G, A#, D, E — sounds, with no buzz and no accidental open string.
Another way to play Gm6 is the open position, in open position: G string open; D string at fret 2 (middle finger); A string at fret 1 (index finger); E string open. This voicing is comfortable because the fretted notes sit close together, from fret 1 to fret 2, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in Gm6 — G, A#, D, E — sounds, with no buzz and no accidental open string.
Choosing between the voicings of Gm6 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 Gm6 up the neck to any key without changing the shape. When you change chords, pick the voicing of Gm6 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into Gm6 from the chord that comes before it in your song, not the chord on its own, because the move is the skill. On the mandolin, start with the first voicing above and listen for the notes G, A#, D, E in Gm6.
A short practice routine for Gm6 on the mandolin: 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 Mandolin Chord Finder to see the diagram for Gm6 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 Gm6 sound wrong on the mandolin, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Clashing the 6th with the 5th. E sits a whole step above the 5th D, so low voicings can sound muddy. Keep the 6th in a higher octave than the 5th. On the mandolin, start with the first voicing above and listen for the notes G, A#, D, E in Gm6.
Using it as a passing chord only. Gm6 works as a tonic too. Try ending a minor phrase on it and listen to how it colours the resolution. On the mandolin, the open position of Gm6 puts those notes under your fingers in the order the fingering lists them.
Missing one string of a course. Mandolin strings come in pairs, and Gm6 needs both strings of each course to sound. If one string of a pair is muted by a neighbouring finger, the chord sounds thin. Check each course separately by plucking it on its own. On the mandolin, start with the first voicing above and listen for the notes G, A#, D, E in Gm6.
Playing the wrong 6th. The added note is E, a major 6th above the root. Play the flattened 6th and you have a different, much darker sound. On the mandolin, the open position voicing is the place to hear it in Gm6.
Where Gm6 is used
Gm6 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 D# major, the key of F major, the key of A# major. a minor tonic in jazz, where the 6th replaces the 7th as the added note. 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 Gm6 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the mandolin, the open position voicing is the place to hear it in Gm6.
Because Gm6 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 Gm6 in a progression in any key and hear how it connects to the chords around it. On the mandolin, the open position of Gm6 puts those notes under your fingers in the order the fingering lists them.
The same chord on other instruments is covered in Gm6 on guitar, Gm6 on piano, Gm6 on ukulele, and the scales that fit over it are the G major scale and the G minor pentatonic scale. Learning Gm6 on the mandolin and then checking it on another instrument is one of the best ways to fix the notes — G, A#, D, E — in your memory, because the notes stay the same while everything else changes.
Practising Gm6
A short worked example makes Gm6 concrete. Play the four-chord progression C – G – Am – F in C major, the key Gm6 most often resolves toward: C – G – Am – F. Play each chord for one bar at a slow tempo, and listen to how Gm6 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 Gm6 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the mandolin, start with the first voicing above and listen for the notes G, A#, D, E in Gm6.
For a second exercise, play Gm6 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 Gm6 is built for when it acts as a dominant. Finish by playing Gm6 on its own, slowly, and naming each note out loud as you play it: G, A#, D, E. 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 mandolin, the open position voicing is the place to hear it in Gm6.
Frequently asked questions
Is Gm6 major or minor?
Minor. Its 3rd is A#, a minor 3rd above G. The added 6th E does not change that — it only adds colour to the minor triad. On the mandolin, check the first voicing above for that note.
Where is Gm6 used?
Gm6 is a minor tonic in jazz and a colour chord in minor-key songs. It appears as the i chord in minor keys and the iv chord in major keys, often in slow, exposed passages. On the mandolin, check the first voicing above for that note.
How do you play Gm6 on the mandolin?
The first voicing is the open position: frets 0–0–1–0, fingers 0–0–1–0, on the mandolin. That voicing uses the notes G, A#, D, E, and it is the one to learn first. The page above lists more voicings for Gm6, so you can choose the shape nearest the chords around it.
Is Gm6 hard to play on the mandolin?
It depends on the voicing. The first voicing of Gm6 on the mandolin 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 Gm6 on the mandolin?
The open position is the easiest voicing listed for Gm6 on the mandolin: frets 0–0–1–0, fingers 0–0–1–0. Learn that shape first, get every note ringing cleanly, and only then move on to the alternative voicings further up the neck.
