The B minor 7th chord (Bm7) is built from a root note (A), a minor third (C), a perfect fifth (E) and a minor seventh (G):
- Type: tetrad.
- Formule: 1 ♭3 5 ♭7.
- Music notes: A (1) F# (♭3) D (5) B (♭7).
- Chords to play with: v (F#m7).
Bm7 chord [Musical explanation]
The A minor seventh chord is a tetrad with formula 1 – ♭3 – 5 – ♭7. Therefore, to build it we need B (1), D (♭3), F# (5) and A (♭7):
This is due to the fact that a minor seventh chord is made up of 3 third intervals:
- A minor interval (3 half steps between the 3rd and root).
- A major inteval (4 half steps between the 5th and 3rd).
- A minor inteval (3 half steps between the 7th and 5th).
If we apply this principle to the Bm7 chord we obtain that:
- D is the minor third of B because it is 3 half steps above the root.
- F# is the perfect fifth of B because it is 4 half steps above the 3rd.
- A is the minor seventh of B because it is 3 half steps above the 5th.
Thus, this confirms that B minor seventh chord is defined by:
Root (B) – Minor Third (D) – Perfect Fifth (F#) – Minor Seventh (A)
To sum up, in order to build the Bm7 chord we need to add the minor seventh (flat 7th) to the B minor chord.
Bm7 Guitar Chord
The Bm7 chord guitar has the following shape on the fretboard:
Let’s analyze in detail this chord diagram above to make sure that we understand how to play the Bm7 on guitar.
Let’s start by analyzing the 2 circles in blue, which indicate that on the strings 4 (D) and 2 (B) we have to place the fingers 3 (ring) and 2 (middle). In this case we need to play a barre chord, so we have to use as well the index finger (1) to press down the strings from 5 to 1.
Note by the way the number 2 in black on the left that indicates on which fret we start playing the chord.
On the other hand, at the top we see that we have the characters:
X B F# A D F#
This simply means that in the:
- Sixth string there is no sound.
- Fifth string sounds the B note.
- Fourth string sounds the F# note.
- Third string sounds the A note.
- Second string sounds the D note.
- First string sounds the F# note.
And at the bottom we find the numbers:
1 5 ♭7 ♭3 5
This indicates that in the:
- Sixth string There is no number because there is no sound.
- Fifth string sounds the root (1).
- Fourth string sounds the perfect fifth (5).
- Third string sounds the minor seveth (♭7).
- Second string sounds the minor third (♭3).
- First string sounds the perfect fifth (5).
⚠️ Important: it is not mandatory to memorize all this information to play the Bm7 chord on guitar. But it is highly recommended to know it in order to understand the musical theory behind each chord.
