Augmented chord

An augmented chord is generally composed using a root/1st, major 3rd and an augmented 5th (or R/1-3-♯5) intervals played simultaneously, however any chord with a raised interval can be given the name "augmented" followed by the interval being raised (ie: Caug6). If there is no number following the aug then it is presumed to be an augmented triad (R/1-3-♯5). Generally written as C⁺ or Caug, it is good practice to simply use an upper case C and a super scripted plus symbol ⁺ (ie: C⁺) to represent it in writing.

The tonality of an augmented chord is dissonant, non-centered and unstable, as opposed to a major chord which is stable and resolved.
