Seventh Chords

Let’s look at how to play a D7 (D seventh) chord on the piano. We’ll also learn the pattern for playing any seventh chord.

What Are Seventh Chords?

Seventh chords are major chords with an added note. The added note is the seventh note of the matching major scale, lowered 1/2 step.

So to build a seventh chord, we’ll start by building a 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).

Then we’ll find the seventh note of the matching major scale and lower it 1/2 step.
