Looking for a harmonically ambiguous chord to add a little mystery to your band’s latest hit single? Or maybe you are listening to a favorite tune and are jarred by a pretty bizarre harmony starring an augmented fifth? Look no further than the rarely used and incredibly underappreciated augmented chord.

From David Bowie to the Beatles, and even a little Broadway, the augmented triad is like that one wacky cousin that no one talks about, but you can’t help liking once you get to know him!

Hearing Augmented

This interesting chord built on two major triads provides a very unique sound that does not occur naturally in the diatonic scale. This triad is often used to create ambiguity and atonality in a work by functioning as a substitute dominant, or is found in the harmonic minor scale as the chord built on the third degree of the scale. Since many of our favorite tunes stubbornly and consistently stay harmonically simple by sticking to four basic chords, adding in the augmented triad brings a bit of interesting flavor to a song.

The Beatles, well known for their harmonic experimentation, have a few tunes that delve into the augmented realm. “All My Loving” is an excellent example, with augmented chords in the chorus (first time at [0:54]):

However, most contemporary popular songs use the augmented chord sparingly, if at all. You will find these more complex harmonies in the rock songs of earlier years and peppered throughout jazz and blues.

In Leslie Gore’s “It’s My Party”, the augmented triad is featured prominently under “cry if I want to” in the chorus. The “+” means “augmented” and is used interchangeably with “aug”. Both will be used in this article, and you will see both in lead sheets. Listen for the augmented chords at [0:08] and all the other choruses:

It’s my party and I’ll
Cry if I want to, Cry
If I want to cry
If I want to

Building the Augmented Triad

How do you create the augmented triad? Is it crazy difficult?

No, for all its atonal ambiguity, the augmented triad is simple.

Start with a major third:

Major third interval

Once you have your major third, build another major third on top:

C augmented chord

The result is two major thirds stacked on top of each other, and an augmented fifth interval between the bottom and the top notes.

Now listen to the augmented triad a few times:

What makes this unique sound? This sound differs from the familiar sounds of a major triad and a minor triad. Listen to the augmented triad compared to the major and minor triads:

Comparing major, minor, and augmented chords

Typically, when we are listening to the chord progressions of our favorite Top 40 tunes, the chords contain either a perfect fifth interval (as in major and minor chords), or occasionally a diminished fifth interval (as in diminished chords). This helps the chord progression move forward, notably in familiar chord progressions like I-IV-V-I or I-V-vi-I.

However, the augmented triad has an augmented, or raised, fifth:

Augmented fifth interval

The raised fifth gives the song a definite harmonically-ambiguous, almost “spacey” type of sound.

Learn How to Pick out the Augmented Triad

In our previous article about diminished triads, we touched upon three different ways to hear the diminished chord in a chord progression:

  1. Learning by rote
  2. Learning by arpeggiation and audiation
  3. Listening to chord quality

Depending on your instrument or voice type and musical training, you may find one way easier than another. Most musicians find that the third way, learning a chord through sounds associated with a specific chord quality, is the quickest and easiest way to learn a chord, especially a chord as distinct as the augmented triad. But we’ll chat about all three methods here.

1. Learning By Rote

Learning how to distinguish between chords by rote is very easy for musicians that play harmonic instruments like keyboards or piano, mallet instruments, and guitar. Because they play chords on a regular basis, many times the unique sound of a chord is easily memorized. Jazz players have the biggest advantage when it comes to recognizing augmented triads since the jazz and blues often delve much deeper into complex harmonic vocabulary than most pop music styles.

For instrumentalists like drummers, trumpet or saxophone players, or even singers, because they focus primarily on rhythm or melody when they play, being able to recognize a chord on the first listen by ear can be very difficult. In fact, it’s very well-known that while percussionists have an almost insane and uncanny ability to quickly repeat numerous dizzying difficult polyrhythms, they often struggle with harmony.

Singers or melodic instrumentalists might also struggle with listening for unusual chords, although harmonic ear training exercises are often part of their musical training.

To learn the augmented triad by rote, you would listen and play the augmented triad on a regular basis, internalizing the sound.

Augmented Triad Practice

  1. Listen to the augmented triad
  2. Play the chord on a keyboard instrument or guitar
  3. Practice the chord within a chord progression
  4. Repeat practice on a daily basis

Practice along and learn how the augmented chord functions as a passing tone and more. This piano tutorial also discusses using diminished chords.

2. Learning By Arpeggiation

Learning a chord through arpeggiation usually involves some training in singing, like using solfege. Many singers are very familiar with using solfege (a system of assigning syllables to specific notes) when they learn music theory and ear training skills.

If you’re already familiar with solfege, you can use this when learning how to sing and recognize an augmented chord. If you are unfamiliar with singing solfege, simply sing on “La”.

  1. Listen to the chord and arpeggio
  2. Sing along with the arpeggiated chord
  3. Practice singing the chord without the audio
  4. Transpose to other keys

Arpeggiated G augmented chord

While this method of learning a chord via arpeggiation is helpful in more advanced ear training, most of the time a musician may be trying to simply figure out the chord progressions to their favorite songs. In that case, this is not the most helpful method.

3. Learning by Chord Quality

What is chord quality? Specifically, it is identifying a chord based on whether it is major, minor, augmented, diminished, etc. Musicians often attribute a specific “sound” related to color, timbre, or even feeling, to each chord. While this is not the most scientific way of identifying a chord, it is often the simplest.

In David Bowie’s “Life on Mars?”, the use of the augmented chord adds a sinister oddness to the song in the pre-chorus ([0:37] and [0:45]) and chorus ([0:58], [1:14], and [1:26]):

Ab          E+
But the film is a saddening bore
For she’s lived it ten times or more
C#              A+
She could spit in the eyes of fools

If you have played music for any length of time, you are probably aware that most pop songs sound “happy” because they stay in the major scale. On a very elemental level, we have attributed feelings to specific scales, chords, and intervals in western harmony. Interestingly enough, these societal emotional attributions to pitch do not necessarily translate well to other cultures, but they work well for our purposes here.

For example, listen to the major chord compared to the augmented chord below:

C major vs augmented chord

Ask yourself the following questions:

  1. How did the major chord sound compare to the augmented chord?
  2. What timbres, tone qualities, or even feelings did you feel when listening to the major chord? The augmented chord?
  3. Which chord would be considered “happy”?
  4. Which chord do you hear most often?
  5. Which chord seems more harmonically ambiguous? Why?

Now compare the augmented chord to the minor chord:

C minor vs augmented chord

Ask yourself:

  1. How did the minor chord sound compare to the augmented chord?
  2. What timbres, tone qualities, or even feelings did you feel when listening to the minor chord? The augmented chord?
  3. What feelings would you assign the minor chord? The augmented chord? Why?
  4. Which chord do you hear most often in popular music or even film music?

Learning how to compare different types of chords in relation to each other is one way to identify which chord is the augmented chord in a progression.

In Cabaret’s “Maybe this Time”, you can hear how the augmented chords are used to transition stepwise and build into the lines “I’ll be lucky” [0:15] and “For the first time” [0:27]:

This popular Broadway song demonstrates just one way that you might use the augmented triad. Because the song has very distinct jazz flavor, there is a rich harmonic palette for the listener to enjoy.

The Beatles once again master the augmented chord on their song “From Me to You”. Notice how the song harmonically builds starting on “I got arms that long to hold you”, culminating with characteristic Beatles harmony on the augmented chord on “satisfied” at [0:47].

A Little Bit of Listening Practice

Check out the example below. You want to practice listening for the augmented chord sound. These examples are based on popular musical examples that we have listened to already.

For each of the musical examples:

  1. Listen to the chord progression a few times
  2. After you listen to the chord progression, try to identify which chords are augmented
  3. Check your answers below

Example 1:

Show answer

C – F – D7 – G – G+ The Beatles augmented chords

Example 2:

Show answer

Bb – Gm – G+ – Eb- G7 Life on mars david bowie augmented chords

How did you do? Were you able to identify the augmented triad in the chord progression?

If not, don’t worry. Developing an ear for chords takes practice. Keep listening to the examples above, play along with your instrument, and start adding in augmented triads when you jam with your friends. Because the augmented chord can substitute easily for a dominant chord, you might find that it is actually fun to change up your sound with a little raised fifth.

Enhance Through Augmentation!

While you probably won’t encounter the augmented triad too often in the Top 40 hits on the radio, you can learn how to use augmented chords in your playing to great effect.

Take a cue from David Bowie and experiment with placing augmented chords strategically to give your chord progressions that spacey, almost supernatural feel, or make like the Beatles and use the augmented chord for harmonic experimentation.

Practice the ear training method that works best for you to learn how to listen for augmented triads in music. Practice makes perfect (or at least a little better) so enjoy the singular strangeness of the augmented triad and rock on!
