Augmented Chords

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.
