The C♭ minor 7th chord (C♭m7) is built from a root note (C♭), a minor third (E♭♭), a perfect fifth (G♭) and a minor seventh (B♭♭):
- Type: tetrad.
- Formule: 1 ♭3 5 ♭7.
- Music notes: C♭ (1) E♭♭ (♭3) G♭ (5) B♭ (♭♭7).
- Chords to play with: v (G♭m7).
C♭m7 chord [Musical explanation]
The C♭ minor seventh chord is a tetrad with formula 1 – ♭3 – 5 – ♭7. Therefore, to build it we need C♭ (1), E♭♭ (♭3), G♭ (5) and B♭♭ (♭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 C♭m7 chord we obtain that:
- E♭♭ is the minor third of C♭ because it is 3 half steps above the root.
- G♭ is the perfect fifth of C♭ because it is 4 half steps above the 3rd.
- B♭♭ is the minor seventh of C♭ because it is 3 half steps above the 5th.
Thus, this confirms that C♭ minor seventh chord is defined by:
Root (C♭) – Minor Third (E♭♭) – Perfect Fifth (G♭) – Minor Seventh (B♭♭)
To sum up, in order to build the C♭m7 chord we need to add the minor seventh (flat 7th) to the C♭ minor chord.
C♭m7 Guitar Chord
The C♭m7 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 C♭m7 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 finger) and 2 (middle). In this case we have 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 1 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 C♭ G♭ B♭♭ E♭♭ G♭
This simply means that in the:
- Sixth string there is no sound.
- Fifth string sounds the C♭ note.
- Fourth string sounds the G♭ note.
- Third string sounds the B♭♭ note.
- Second string sounds the E♭♭ note.
- First string sounds the G♭ 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).
