Second Chords

Let’s look at how to play an A2 (A second) chord on the piano. We’ll also learn the pattern for building any second chord.

What Are Second Chords?

Second chords are major chords with an added note. The added note is the second note of the matching major scale.

So to build a second 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 to convert a major chord into a second chord, we’ll add the second note of the same scale to the chord.
