A Flat Augmented Chord on the Guitar (Ab+) – Diagrams, Finger Positions, Theory

The A flat augmented chord (Ab+) is an A flat Major chord, with a raised 5th. It contains the notes Ab, C and E.

Each note of the Ab augmented chord is separated by an interval of a Major 3rd. Because every interval inside the Ab augmented chord is identical, it is known as a symmetrical chord. Another way of looking at this is as follows – If you play an augmented chord starting from any of the notes inside the A flat augmented chord, the new chord will contain the same notes as the A flat augmented chord:

  • The Ab augmented chord contains the notes Ab, C, E
  • The C augmented chord contains the notes C, E, Ab
  • The E augmented chord contains the notes E, G# (same as Ab), B# (same as C)
