How to Play a Cm2 Chord on the Piano

Minor Second Chords

Let’s look at how to play a Cm2 (C minor second) chord on the piano. We’ll also learn the pattern for building any minor second chord.

What Are Minor Second Chords?

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

So to build a minor second chord, we’ll start with a minor chord. Minor chords are built using the first, third and fifth notes of the matching minor scale. Another way to build a minor chord is to take the matching major chord and lower the middle note 1/2 step.

To convert the minor chord into a minor second chord, we’ll add the second note of the matching major or minor scale (the second note of both these scales will be the same, so use whichever one is easier).

You can use this pattern to build any minor second chord. Just build a minor chord, then add the second note of the matching major scale.

A Cm2 chord uses the same notes as a Cmadd9 chord. A Cmadd9 chord is a minor chord with an added note. The added note is the ninth note of the matching major scale. The ninth note is the same note as the second note of the scale, just one octave up. So the Cmadd9 and Cm2 chords have the same notes, just in a different order:

Cm2: C – D – E♭ – G
Cmadd9: C – E♭ – G – D
