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 a Cm7 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.

Note by the way the number 4 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 minor third (5).
