Fifths Chords
Let’s look at how to play a D5 (D fifth) chord on the piano. We’ll also learn the pattern for building any fifth chord.
What Are Fifth Chords?
Fifth chords are built using the first and fifth notes of the matching major scale.
Technically, fifth chords aren’t “chords” since the definition of a chord is three or more notes, sounded together. Fifth chords are only two notes, but we’ll call them chords since they behave like chords.
One easy way to build fifth chords is to think of them as major or minor chords without the middle note.
How to Play a D5 Chord
Let’s look at how to build a D5 chord on the piano. We can play the first and fifth notes of our D major scale: D – A. Or we can start with a D major chord (D – F♯ – A) and leave out the F♯: D – A.
So to play a D5 chord, we’ll play:
D – A

You can use this pattern to build any fifth chord. Just play the first and fifth notes of the matching major scale. Or start with the matching major chord and leave out the middle note.

Conclusion
Now you know how to build a D5 chord, and you can use that knowledge to build any other fifth chord on the piano!
