How to Play a C2 Chord on the Piano

Second Chords

Let’s look at how to play a C2 (C 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 play a second chord, we’ll start with 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).

To convert the major chord into a second chord, we’ll add the second note of the matching major scale.

You can use this pattern to build any second chord on the piano!

Build a major chord, then add the second note of the matching major scale.

Second chords use the same notes as “add9” chords. An add9 chord is a major chord with an added major ninth. A major ninth is the same note as the second note of the scale, just one octave up. So the Cadd9 and C2 chords have the same notes, just in a different order.
Cadd9: C – E – G – D
C2: C – D – E – G
