G# Chord on Ukulele
G# = G# – C – D# (Root, Major 3rd, Perfect 5th)
G# major has to be built entirely from fretted notes, the same problem F# major runs into a half step below it: none of the open GCEA strings land on G#, C, or D#, so the whole triad needs fingers on every string. One workable voicing frets the G string at the first, the C string at the third, the E string at the fourth, and the A string at the third, spreading across a three-fret window that's compact for a fully closed shape even if it takes real coordination to place all four fingers at once. Two strings, C and A, land on the identical third fret without being adjacent, which is why this shape needs four independent fingers rather than a barre — a barre at the third fret would also catch the G and E strings and pull in the wrong notes.
In standard music notation this chord is almost always written as Ab major rather than G# major, since Ab's four-flat key signature is far more common than G#'s theoretical eight-sharp equivalent, though ukulele players following guitar-style sharp-based chord charts will still meet it spelled this way. Functionally, G# major's most frequent real job is as the V chord of C# minor, a legitimately common minor key since it's the relative minor of E major — an instrument staple — so any E major song that dips into its vi chord for a darker verse often resolves that detour with a G# or G#7 dominant. It also turns up as a bIII or borrowed color chord inside E major and B major progressions, adding a brief unexpected brightness before the harmony returns to more familiar diatonic ground.

How to Practice It
Since every string carries weight, build the shape one finger at a time before attempting a full strum: place the index finger on the G string's first fret, the ring finger on the C string's third fret, the pinky on the E string's fourth fret, and the middle finger on the A string's third fret, adjusting whichever assignment feels most stable for your own hand. Because there's no open string to anchor the ear, pluck each string separately first to confirm none of the four notes is buzzing or going dead before combining them into a strum. Given how rarely this exact shape gets approached from a neighboring open chord, practice releasing and refretting it from a resting hand position repeatedly, rather than expecting to slide into it from something more familiar. Once the four-finger version feels secure, it's worth learning the barred alternative higher up the neck as a backup, since a fully closed low-position shape like this one is genuinely one of the more demanding common triads on the instrument.
Common Progressions
- V – i (G# – C#m), resolving into the key of C# minor
- bIII – IV, using G# as a borrowed color chord in E major
- V7 – i, with G#7 sharpening the pull into C# minor
- bVI – V – i, a minor-key cadence figure in C# minor using G# as the dominant
FAQ
- Is G# major the same as Ab major?
- Yes, enharmonically — they're the identical set of notes and the identical shape on ukulele, but standard notation almost always spells this chord as Ab, since its four-flat key signature is far simpler than G#'s theoretical sharp-heavy equivalent.
- Where does G# major show up harmonically?
- Most often as the V chord of C# minor, the relative minor of the common uke key E major, plus as a borrowed bIII color chord inside E major or B major progressions.
- Why does G# major need all four fingers on ukulele?
- None of the open GCEA strings sound G#, C, or D# — the chord's three notes — so every string has to be fretted, the same situation F# major runs into a half step lower.
- Is there an easier way to play G# major?
- A four-string barre further up the neck reproduces the same three notes with a single finger doing the covering work, though it moves the chord to a higher position that isn't always convenient mid-song.
- Why can't the C and A strings' shared third-fret notes be covered with a barre?
- Because the G and E strings, which sit between and around them, would also be caught by a barre at that fret and would introduce notes that don't belong to the G# major triad, forcing four independent fingers instead.
