String by string
What each string does in this shape, and which note of the chord it sounds. This is what to listen for when you pluck them one at a time.
| String | Fret | Finger | Note | In the chord |
|---|---|---|---|---|
| 4th (G) | fret 3 | little | A♯4 | third |
| 3rd (C) | fret 2 | middle | C𝄪4 | sharp fifth |
| 2nd (E) | fret 2 | ring | F♯4 | root |
| 1st (A) | fret 1 | index | A♯4 | third |
One string at a time: a chord strummed into a microphone is several notes at once, and a single string is something the page can hear exactly. A string in tune but on the wrong fret, or deadened by the finger beside it, shows up here and not on a tuner. Tap a string to check it again.

The same 3 notes, somewhere else on the neck. A different shape puts a different note on top, so each one colours the chord slightly differently — and one of them is usually nearer the chord you are coming from.

If the usual shape is too hard for now
3225 is F♯aug without the full barre — fewer strings, the same chord. It is a real voicing, not a cheat, and plenty of players keep using it.
Holding it cleanly
Press just behind each fret, not on top of it and not in the middle of the gap: that is where the least pressure gives a clean note.
The notes in F♯aug
A augmented chord is built from the root (1), 3 and ♯5 of its root’s major scale. From F♯ that gives F♯ – A♯ – C𝄪 (D). A major chord with its fifth raised a semitone. Its three notes are evenly spaced, so any of them can be the root.
The same root, other chords: F♯ major, F♯m, F♯7, F♯maj7, F♯m7, F♯sus2, F♯sus4, F♯dim.
Frequently asked questions
What notes are in a F♯aug chord?
F♯ augmented is three notes: F♯ – A♯ – C𝄪 (D) — the root, 3 and ♯5 of the F♯ major scale. On ukulele the shape 3221 sounds A♯4, C𝄪4, F♯4 and A♯4, so some of those notes appear more than once.
What is the easiest way to play F♯aug on ukulele?
The usual shape is 3221 — a shape at the 1st fret, with four fingers. If that is out of reach for now, 3225 is the same chord without the full barre.
Is F♯aug the same chord as G♭aug?
Yes — on ukulele they are the same frets and the same sound. F♯ and G♭ are two names for one pitch, and which name a songbook prints depends on the key: a piece in a sharp key writes F♯aug, a piece in a flat key writes G♭aug.
What is the difference between F♯aug and F♯?
One note. F♯aug is F♯ with its fifth raised a semitone, to C𝄪. The three notes are then exactly four semitones apart, so the chord has no clear root and sounds as if it is about to move — usually up, to the chord a fourth above.
