About Ab augmented
The notes of Ab augmented are Ab (root), C (major third) and E (augmented fifth). Its interval formula is 1 – 3 – #5. It is an augmented chord: it stacks two major thirds and sounds ambiguous and suspended, as if it wants to resolve.
Ab augmented has no standard open shape in the CAGED system, so its 28 voicings are sorted only by difficulty and position on the neck. Another way to write Ab augmented is G# augmented (the same piano key, with a different name). Ab augmented is the usual choice.
