C♭ chord [Musical explanation]

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

what notes are in the Cb chord

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

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

If we apply this principle to the C♭ chord we obtain that:

  • E♭ is the major third of C♭ because it is 4 half steps above the root.
  • G♭ is the perfect fifth of C♭ because it is 3 half steps above the 3rd.

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

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

In other words the Cb major chord is the same as the C major 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 2 (middle), 3 (ring finger) and 4 (pinky). 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 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:

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 major third (3).
  • First string sounds the perfect fifth (5).

⚠️ Important: it is not mandatory to memorize all this information to play the Cb chord on guitar. But it is highly recommended to know it in order to understand the musical theory behind each chord.
