G Melodic Minor Scale: Notes, Chords, and How to Play It
The G melodic minor scale sits at the intersection of flat and sharp territory — it contains one flat (Bb, inherited from the natural minor) that is raised away, and one sharp (F#) as its leading tone. With only two accidentals, G melodic minor is one of the most accessible keys for exploring the melodic minor sound, and the key of G sits comfortably on both piano and guitar.
What Makes the Melodic Minor Different?
The melodic minor scale can be thought of as a major scale with a flattened third — or, equivalently, a natural minor scale with its sixth and seventh degrees raised. This dual identity gives it a unique character: minor enough for emotional depth, but with the strong leading tone and smooth voice leading that natural minor lacks.
For a full comparison of all three minor scale types, see Minor Scales: Natural, Harmonic, and Melodic.
Notes of the G Melodic Minor Scale
The G melodic minor scale contains seven notes:
G – A – Bb – C – D – E – F#
Starting from G, the scale follows the melodic minor interval pattern — W – H – W – W – W – W – H — and arrives back at G one octave higher. Compared to G natural minor (G–A–Bb–C–D–Eb–F), the sixth and seventh degrees are raised: Eb becomes E and F becomes F#.
| Degree | Note | Interval from Root | Step to Next |
|---|---|---|---|
| 1 (Root) | G | Unison | Whole step |
| 2 | A | Major 2nd | Half step |
| 3 | Bb | Minor 3rd | Whole step |
| 4 | C | Perfect 4th | Whole step |
| 5 | D | Perfect 5th | Whole step |
| 6 | E | Major 6th | Whole step |
| 7 | F# | Major 7th | Half step |
| 8 | G | Octave | – |
The half steps fall between A–Bb (degrees 2–3) and F#–G (degrees 7–8). The only difference from G major (G–A–B–C–D–E–F#) is the flattened third: Bb instead of B. This is why the melodic minor is often described as “a major scale with a flat three.”
Classical vs Jazz Usage
In classical theory, the melodic minor descends differently — reverting to the natural minor form:
- Ascending: G – A – Bb – C – D – E – F# – G
- Descending: G – F – Eb – D – C – Bb – A – G
In jazz and contemporary music, the ascending form is used in both directions. This article focuses on the ascending (jazz) form, which is the version used in the Interactive Chord Finder.
G Melodic Minor on Piano
On the piano, G melodic minor uses five white keys (G, A, C, D, E) and two black keys (Bb and F#). The black keys sit at opposite ends of the scale — Bb near the bottom and F# near the top — creating a distinctive physical shape that is easy to memorise.
Right hand fingering (ascending): 1 – 2 – 3 – 1 – 2 – 3 – 4 – 5 (thumb crosses under after Bb, then fingers walk up to G)
Left hand fingering (ascending): 5 – 4 – 3 – 2 – 1 – 3 – 2 – 1 (after the thumb plays D, the third finger crosses over to E)
The two black keys are separated by four white keys, so each hand has a clear “landmark” at either end of the octave.
G Melodic Minor on Guitar
On guitar, G melodic minor can start on the 3rd fret of the 6th string, a familiar position for guitarists who know their G minor barre chord.
Third position (low to high):
| String | Fret | Note |
|---|---|---|
| 6th (E) | 3 | G |
| 6th (E) | 5 | A |
| 6th (E) | 6 | Bb |
| 5th (A) | 3 | C |
| 5th (A) | 5 | D |
| 4th (D) | 2 | E |
| 4th (D) | 4 | F# |
| 4th (D) | 5 | G |
This pattern covers one octave from G on the 6th string to G on the 4th string. The fingering sits comfortably in third position with only a brief shift down to the 2nd fret for E.

Diatonic Chords in G Melodic Minor
Stacking thirds on each degree:
| Degree | Chord | Quality | Notes |
|---|---|---|---|
| i | Gm | Minor | G – Bb – D |
| ii | Am | Minor | A – C – E |
| III+ | Bbaug | Augmented | Bb – D – F# |
| IV | C | Major | C – E – G |
| V | D | Major | D – F# – A |
| vi° | Edim | Diminished | E – G – Bb |
| vii° | F#dim | Diminished | F# – A – C |
The augmented III chord (Bbaug) and the two diminished triads distinguish this from the natural minor chord pattern.
Seventh Chords
| Degree | Chord | Quality | Notes |
|---|---|---|---|
| imMaj7 | Gm(maj7) | Minor-major 7th | G – Bb – D – F# |
| ii7 | Am7 | Minor 7th | A – C – E – G |
| III+maj7 | Bbmaj7#5 | Augmented major 7th | Bb – D – F# – A |
| IV7 | C7 | Dominant 7th | C – E – G – Bb |
| V7 | D7 | Dominant 7th | D – F# – A – C |
| viø7 | Em7b5 | Half-diminished | E – G – Bb – D |
| viiø7 | F#m7b5 | Half-diminished | F# – A – C – E |
The IV7 chord (C7) is the Lydian dominant sound — C7 chords that do not resolve conventionally can be approached using C Lydian dominant (the fourth mode of G melodic minor). The V7 (D7) provides standard dominant function back to Gm.
Modes of the Melodic Minor
| Mode | Starting Degree | Name | Character |
|---|---|---|---|
| 1st | G | Melodic minor | Smooth minor |
| 2nd | A | Dorian b2 | Dark, Phrygian-like |
| 3rd | Bb | Lydian augmented | Bright, expansive |
| 4th | C | Lydian dominant | Bright but bluesy |
| 5th | D | Mixolydian b6 | Bittersweet major |
| 6th | E | Locrian #2 | Dark, half-diminished |
| 7th | F# | Altered / Super Locrian | Tense, unstable |
The C Lydian dominant mode is particularly useful for jazz musicians working with C7 chords. The F# altered scale provides essential vocabulary over F#7alt chords.
Common Chord Progressions in G Melodic Minor
| Progression | Chords | Used in |
|---|---|---|
| i – IV – V – i | Gm – C – D – Gm | Jazz, fusion |
| i – II – V – i | Gm – Am – D7 – Gm | Jazz minor ii-V-i |
| i – ii – V – i | Gm(maj7) – Am7 – D7 – Gm(maj7) | Jazz ballads |
| i – IV7 – viiø7 – III+ | Gm – C7 – F#m7b5 – Bbaug | Modern jazz |
| i – iv – V7 – i | Gm – Cm – D7 – Gm | Classical minor |
Relationship to Other Minor Scales
| Scale | Notes | 6th | 7th |
|---|---|---|---|
| G natural minor | G–A–Bb–C–D–Eb–F | Eb (minor 6th) | F (minor 7th) |
| G harmonic minor | G–A–Bb–C–D–Eb–F# | Eb (minor 6th) | F# (major 7th) |
| G melodic minor | G–A–Bb–C–D–E–F# | E (major 6th) | F# (major 7th) |
The harmonic minor raises only the seventh (F to F#), creating the augmented second (Eb to F#). The melodic minor raises both (Eb to E, F to F#), producing smooth whole-step motion from D to E to F# to G.
Songs and Repertoire
- “Round Midnight” – Thelonious Monk (passages in G melodic minor territory)
- “Summertime” – Gershwin (often performed with melodic minor inflections in G minor)
- Classical sonatas – Mozart and Beethoven frequently wrote in G minor with melodic minor ascending passages
- Film scores – G minor is a popular key for dramatic underscore, and melodic minor adds sophistication
Practice Tips
Notice the symmetry. The two accidentals (Bb and F#) sit at opposite ends of the scale, creating a balanced feel under the fingers.
Compare with natural minor. Play G natural minor, then G melodic minor. The raised E and F# brighten the upper portion dramatically.
Play in thirds. G–Bb, A–C, Bb–D, C–E and so on. This reveals how the augmented third (Bbaug) emerges from the scale.
Work on the C Lydian dominant. Starting the scale from C produces one of the most versatile jazz modes — practise it over C7 chords.
Use a metronome. Start at 60–80 BPM and increase speed only when every note is clean and even.
Try It Yourself
Open the Interactive Chord Finder, select G as the root and Melodic Minor (asc) as the scale. You will see every note highlighted on the piano keyboard or guitar fretboard, the step pattern visualised as intervals, and all diatonic chords laid out in a table — ready to play and explore.
