Augmented chords are chords built from
two stacked major thirds, creating an augmented fifth above the root
of the chord. Another way to think of it would be having a major
chord with a raised fifth. The chord symbol for and augmented chord
is usually a plus sign (+) or “aug” added after the chord letter
name, for example, C+ or Caug.
Augmented chords can resolve in several
ways. The following examples show augmented chords used in various chord
progressions.
