Ab6 Ukulele Chord
Ab6 is the A flat sixth chord. It has four notes: A flat, C, E flat and F. The main shape is a small barre at the 1st fret with the ring and pinky at the 3rd, and it is the same grip as A6 moved one fret toward the nut.
A three string barre at the 1st fret with ring and pinky at the 3rd. The movable sixth grip at its lowest home.
How to play Ab6 on ukulele, step by step
- Index finger: press flat across the G to E strings at fret 1
- Ring finger: 3rd fret, C string
- Pinky finger: 3rd fret, A string
- Strum all four strings.
Nothing in this shape is specific to A flat. It is the movable sixth grip at its lowest position: slide it up one fret and the same fingers play A6, up three and they play Bb6.
More ways to play Ab6
There are 3 common Ab6 shapes: the standard one at the top of the page, plus these further up the neck. You only ever need one. Tap any card to hear it.

Middle of the neck and well balanced, with the root inside the chord rather than at the edge.

Tight and bright at the top of the neck. Best saved for an ending.
If it sounds muddy or buzzy
- Notes under the barre drop out
- The index lies across three strings at the 1st fret, the stiffest spot on the neck. Keep it right behind the fret wire and roll it slightly onto its edge.
- The A string is quiet
- The pinky at the 3rd fret carries the fifth. Press with the fingertip and sound the string alone before strumming the chord.
- The chord sounds choked
- Nylon strings near the nut need firm, accurate pressure. Squeeze from the thumb behind the neck rather than clamping the whole hand.
What makes it an Ab6
A♭ · C · E♭ · F 1 3 5 6
Ab6 is an A flat major triad (A flat, C, E flat) with a sixth added: the F, nine half steps above the root. Nothing is taken away, so the chord still sounds like A flat, just rounder and softer.
The same four notes read from F spell Fm7. A ukulele has no bass string to pick the name, so the surrounding chords do. A flat is a horn and piano key, so a ukulele player usually meets this chord in jazz and soul charts rather than in songbook keys.
Ab6 vs Abmaj7
Ab6 adds an F to the A flat triad; Abmaj7 adds a G. A whole step below the root against a half step below it: one settles, the other hangs.
Both belong to the flat key world of horns and keys. When a chart in A flat wants a final chord that does not push anywhere, the sixth is the usual choice.

Yes, one chord with two spellings. Flat keys write Ab6, and that is the name used here.
Is Ab6 the same as Fm7?
The four notes are the same: A flat, C, E flat and F. With no bass note on a ukulele, context decides which name your ear picks.
Is Ab6 hard to play?
It is a three string barre at the 1st fret plus two fingers. The 1st fret needs the firmest press on the neck, but the barre is short, which keeps it manageable.
