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.
What Are Minor Seventh Chords?
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.
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.
To play this chord with your right hand, use fingers 1 – 2 – 3 – 5. Or to play it with your left hand, use fingers 5 – 3 – 2 – 1 (thumbs are 1’s).

So a Bmaj7 chord is: B – D♯ – F♯ – A♯
So a Bm7 chord is: B – D – F♯ – A
