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):

what notes are in the Cbm7 chord

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.

Let’s analyze in detail this chord diagram above to make sure that we understand how to play the C♭m7 on guitar.

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:

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).
