Aug chords

The aug (augmented) chords are among together with the dim chord two groups of triads that are much less common than major and minor. The aug chord is sometimes written with a plus (+) symbol, for example C+.

Then these chords occur in songs, they are for the most part used sporadically, often between two major chords, and could then give subtle interest to the harmony of the song (see some suggestion of progressions att the end of the page).

To summarize the aug chord from a theoretical point of view, the chord consists of a root, a major third and an augmented fifth.

You only need to learn a moveable shape to play all aug chords:
