The Ab augmented chord is usually written Abaug and uses the notes Ab, C and E. The lowest voicing starts at fret 5 and the highest reaches fret 14.
Every interval between neighbouring notes is a major third, which is why the chord sounds symmetrical. For lead lines, reach for the Ab augmented scale: it holds each note of the chord, so every chord tone is available. The logic of stacking thirds is explained in how chords are built.
Start the drum loop in the practice tool at the top, choose a tempo and repeat the chord until it lands on the beat.
Ab augmented guitar chord is also written as Abaug, Ab+, Ab(#5) or Abmaj(#5).
