A#aug Ukulele Chord

A#aug is an augmented triad of A#, D and F# whose raised fifth gives it a hanging, unresolved tension. It adds a cinematic, suspenseful color and slips smoothly between two chords, and the symmetrical shape repeats every four frets to also name Daug and F#aug.

How to Play This Chord

Position your fingers on the fretboard as shown in the diagram. The vertical lines represent the four strings, from the top G string (left) to the A string (right), and the horizontal lines are the frets. Numbers inside the dots indicate which finger to use: 1 (index), 2 (middle), 3 (ring), 4 (pinky). An X means don't play that string; an O means play it open. A bar spanning multiple strings means one finger presses across all of them at once — this is known as a barre chord.

Tips & Tricks

Barre your middle finger across the C and E strings at fret 2, set the ring finger on the high G string at fret 3, and place the index on the A string at fret 1. The small barre is the real difficulty — roll the middle finger slightly onto its side and press close to the fret so both covered strings sound and the bottom note stays clean.
