Augmented Chords
Let’s look at how to play augmented chords on the piano. Once we know the pattern for building an augmented chord, we can apply that pattern starting on any note, to build augmented chords.
How to Play an Augmented Chord
To play an augmented chord, build a major chord, and then raise the upper-note 1/2 step.
C Augmented Chord
Let’s build a C augmented chord. We’ll start by building a C major chord. Major chords are built using the first, third and fifth notes of the matching major scale (learn how to build a major scale here). So to build a C major chord we’ll play the first, third and fifth notes of a C major scale: C – E – G.
Then we’ll raise the fifth note G by 1/2 step, to G♯.
So to play a C augmented chord, we’d play:
C – E – G♯

You may be wondering, “How do I know if I should label the G♯ as a G♯, or as an A♭? Great question! It comes down to the intervals used to build the chord (learn about piano intervals here).
But the short answer is that augmented chords are built using a root, a major third, and an augmented fifth. since “G” is a fifth up from “C” alphabetically, we need to call this some type of “G”. So we’ll call it “G♯”.
G Augmented Chord
Now let’s build a G augmented chord. We’ll start by building a G major chord, using the first, third and fifth notes of the G major scale: G – B – D.
Then we’ll raise the fifth note D by 1/2 step, to D♯.
So a G augmented chord is:
G – B – D♯

Conclusion
Now you know how to build any augmented chord. Start with a major chord and raise the upper-note by 1/2 step.
Learning patterns on the piano is so much better than memorizing individual notes for chords, because patterns can be applied again and again!
Well explained and detailed. Clear. Concise. Helpful. The world will be filled with more music because you are teaching aspiring pianists how to produce it! Wonderful.
Thank you so much for the encouraging words!
Hullo Julie! I enjoy reading your weekly “lessons”. They are simple, clear and easy to understand. I’ve learnt a lot from your lessons.
The circle of fifths was extremely useful, and so too the lesson on intervals.
Thank you very much.
That’s wonderful, I’m so glad to hear that!
thank you again for your east to understand explanations. I understand the concept but have difficulty where to use them in my improvision of gospel music.
You’re welcome! I only use augmented chords when they’re called for, since they don’t really work well as chord substitutions. Some chord substitutions that do work well for major and minor chords when improvising are: 2, sus2, sus4, and 5 chords. (You can also play these substitutions as inversions, which provides a lot of extra room for creativity.) I hope that helps!
thank you very helpful. i do use 2sus frequently. love the sound. i play mostly hymns and gospel
music but trying to learn to chord
I really like posts recieved about Piano cords and scales, Mam Julie has made it easy to understand for a beginner like me, i m gratefull for her teaching in a student friendly manner
Thank you so much, I appreciate hearing that!
Thank you so much for all the informative content; I really appreciate it. I’ve heard all these chord names for years, even played some of them on the guitar, without really knowing what things like “major seventh” or “sus4” meant. Now, after 15 minutes of reading and a bit of trying things out on the piano, I feel like I’ve got a pretty good handle on how to build all of the basic chords. Wishing you many blessings!
I’m so glad to hear that, thank you so much!
Thanks again, Julie
