The Augmented Triad

The Augmented Triad.

The term “augmented” in chord names is abbreviated to aug or +, as in Caug or C+. Both these mean the same thing: a C chord with a raised (augmented) 5th.
Hence: the terminologies “Augmented” and “diminished” in chord names, always refer to the 5th of the chord. (“major” and “minor” refer to the 3rd of the chord)

The structure of the augmented triad is 1 3 #5

You get these intervals when you stack two major 3rds. From the root (1) to 3 is a major 3rd interval, from 3 to #5 is a major 3rd interval again.
When you go up another major 3rd from the #5, you end back on 1 (the root).

For example: the notes in a Caug chord are C E G#. When you go up a major from G# you land back on the note C

Hence, this is a symmetrical chord: all notes are equal distance (4 fret distances) from one another in the chord and cut the octave into 3 equal parts. (3 x 4 frets = 12 frets)

In a symmetrical chord, you only have 1 chord shape (on each string set) for all inversions of that chord.

Inverting the notes C E G# so the 3rd becomes the lowest note, gives you:

E G# C. The structure: a major 3rd followed by a major 3rd.

Inverting the notes again gives you:

G# C E. The structure: a major 3rd followed by a major 3rd.

The aug shapes for all inversions on all stringsets look like this:


Next week we’ll cover the augmented arpeggio fingerings, and what you can do with these cool-sounding chords.

Hit me up anytime at if you would like me to send you fun backing tracks to solo over with these chords.
You’re on your way to becoming a great guitar player.
Have fun! 🙂


Hit me up anytime at if you have any questions, or if you would like to book a lesson.

These free lessons are cool, but you will never experience the progress, joy, and results that my students experience in lessons when you’re learning by yourself from blogs and videos.

That is why people take lessons: way better results and progress, much more complete information, exposed to way more creative ideas than you can get from a blog or YouTube video.
There is only so much that self-study can accomplish.

If you want to see amazing results and progress in your guitar playing, buy your first lesson here and get started ASAP.
