Minor Seventh Chords

Let’s look at how to build a Bm7 chord on the piano. We’ll also learn the pattern for building any other minor seventh chord here.

What Are Minor Seventh Chords?

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

We can build a minor chord by first building a major chord using the first, third and fifth notes of the matching major scale. Then to turn the major chord into a minor chord, we’ll lower the middle note 1/2 step.

Next, to convert the minor chord into a minor seventh chord, we’ll find the seventh note of the matching major scale, lower it 1/2 step, and add it to the minor chord.

How to Play a Bm7 Chord on the Piano

So to build a Bm7 chord, we’ll start by building a B minor chord. We can build a B minor chord by building a B major chord using the first, third and fifth notes of the B major scale: B – D♯ – F♯, then lower the middle note 1/2 step to turn it into a minor chord: B – D – F♯

Then we’ll find the seventh note of the B major scale, A♯, and lower it 1/2 step to A, before adding it to the chord.

So to play a Bm7 chord, we’ll play:

B – D – F♯ – A

We can use this pattern to build any other minor seventh chord, by building a minor chord and then adding the seventh note of the matching major scale, lowered 1/2 step.
