(3.12) Augmented Chords

The extended chords formed from the augmented triad are listed below. The symbols '#5' and '+' in chord names both indicate the augmenting of the fifth degree.

The augmented triad itself is another symmetric chord type, similar to the dim7 chord in the previous topic.

Its adjacent notes each have an interval of a major third between them (1-3, 3-#5, #5-1). Again this results in augmented chords based on root notes a major third apart containing the same notes in a different order.
