G# Melodic Minor Scale: Notes, Chords, and How to Play It
The G# melodic minor scale is one of the most theoretically demanding keys, featuring a double sharp (F-double-sharp, enharmonic to G). While many musicians prefer the enharmonic equivalent A-flat melodic minor for readability, understanding G# melodic minor builds deep theoretical fluency and demonstrates why enharmonic choices matter. This key appears in advanced classical and jazz contexts where sharp-side key relationships are in play.
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# – B – 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#–B–C#–D#–E–F#), the sixth and seventh degrees are raised: E becomes E# and F# becomes F## (F double sharp).
| Degree | Note | Interval from Root | Step to Next |
|---|---|---|---|
| 1 (Root) | G# | Unison | Whole step |
| 2 | A# | Major 2nd | Half step |
| 3 | B | 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#–B (degrees 2–3) and F##–G# (degrees 7–8). The double sharp (F##) sounds like G on the piano but is spelled this way to maintain the correct interval structure — each scale degree must use a different letter name. The only difference from G# major (G#–A#–B#–C#–D#–E#–F##) is the flattened third: B instead of B#.
The Double Sharp
The symbol ## (double sharp) raises a note by two half steps from its natural position. F## is therefore two half steps above F, which places it on the same pitch as G. While this may seem unnecessarily complex, the spelling preserves the principle that every scale degree occupies its own letter name (G, A, B, C, D, E, F — each represented once).
Classical vs Jazz Usage
In classical theory, the melodic minor descends differently — reverting to the natural minor form:
- Ascending: G# – A# – B – C# – D# – E# – F## – G#
- Descending: G# – F# – E – D# – C# – B – 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 black keys (G#, A#, C#, D#) and the keys that correspond to E# (the F key) and F## (the G key). The scale starts on the black key G#, and the upper portion includes two notes that are enharmonic respellings of white keys.
Right hand fingering (ascending): 3 – 4 – 1 – 2 – 3 – 1 – 2 – 3 (thumb crosses under after B, then again after E#)
Left hand fingering (ascending): 3 – 2 – 1 – 4 – 3 – 2 – 1 – 3 (thumb plays B, fourth finger crosses over to C#)
The physical key pattern is identical to A-flat melodic minor — only the note names differ. Many pianists find it helpful to think of the sound and finger pattern while keeping the theoretical spelling in mind for analysis.
G# Melodic Minor on Guitar
On guitar, G# melodic minor is commonly played starting at the 4th fret of the 6th string.
Fourth position (low to high):
| String | Fret | Note |
|---|---|---|
| 6th (E) | 4 | G# |
| 6th (E) | 6 | A# |
| 5th (A) | 2 | B |
| 5th (A) | 4 | C# |
| 5th (A) | 6 | D# |
| 4th (D) | 3 | E# (F) |
| 4th (D) | 5 | F## (G) |
| 4th (D) | 6 | G# |
This pattern covers one octave. On the fretboard, note names are less critical than finger patterns, so guitarists can focus on the physical shapes while understanding the theory behind the spelling.

| viiø7 | F##m7b5 | Half-diminished | F## – A# – C# – E# |
The IV7 chord (C#7) provides the Lydian dominant sound, and the altered scale from the seventh degree (F##) is theoretically important even if rarely written in this spelling.

Relationship to Other Minor Scales
| Scale | Notes | 6th | 7th |
|---|---|---|---|
| G# natural minor | G#–A#–B–C#–D#–E–F# | E (minor 6th) | F# (minor 7th) |
| G# harmonic minor | G#–A#–B–C#–D#–E–F## | E (minor 6th) | F## (major 7th) |
| G# melodic minor | G#–A#–B–C#–D#–E#–F## | E# (major 6th) | F## (major 7th) |
The harmonic minor raises only the seventh (F# to F##), creating the augmented second (E to F##). The melodic minor raises both the sixth and seventh, producing smooth stepwise motion.
Enharmonic Equivalent
G# melodic minor is enharmonically equivalent to A-flat melodic minor (Ab–Bb–Cb–Db–Eb–F–G). In practice, many musicians prefer the flat spelling for readability. Both produce identical sounds — the choice depends on the harmonic context and key signature of the surrounding music.
Practice Tips
Start with the enharmonic. If G# melodic minor feels overwhelming, practise A-flat melodic minor first (same pitches, simpler spelling), then learn the G# spelling for theoretical completeness.
Understand the double sharp. F## is simply G on the keyboard. The spelling exists to maintain one note per letter name in the scale.
Compare with natural minor. Play G# natural minor, then G# melodic minor. The raised E# and F## brighten the upper portion of the scale considerably.
Play in thirds. G#–B, A#–C#, B–D#, C#–E# and so on. This builds fluency in navigating the accidentals.
Use a metronome. Start at 60–80 BPM and increase speed only when every note is clean.
