C♭m chord [Musical explanation]

The C♭ minor chord is a minor triad with formula 1 – ♭3 – 5. Therefore, to build it we need C♭ (1), E♭♭ (♭3) and G♭ (5):

what notes are in the Cbm chord

This is due to the fact that a minor chord is made up of 2 third intervals:

  • A minor interval (3 half steps between the 3rd and root).
  • A major interval (4 half steps between the 5th and 3rd).

If we apply this principle to the C♭m 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.

Thus, this confirms that C♭ minor chord is defined by:

Root (C♭) – Minor Third (E♭♭) – Perfect Fifth (G♭)

In other words the Cb minor chord is the same as the Cm chord but lowered by a half step.

Let’s start by analyzing the 3 circles in blue, which indicate that on the strings 4 (D), 3 (G) and 2 (B) we have to place the fingers 3 (ring finger), 4 (pinky) 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 3 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♭  C♭  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 C♭ note.
  • Second string sounds the E♭♭ note.
  • First string sounds the G♭ note.

And at the bottom we find the numbers:

1  5  1  ♭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 root (1).
  • Second string sounds the minor third (♭3).
  • First string sounds the perfect fifth (5).
