C#maj7 chord [Musical explanation]

The C# major 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 C#maj7 chord

This is due to the fact that a major seventh chord is made up of 3 third intervals:

  • A major interval (4 half steps between the 3rd and root).
  • A minor interval (3 half steps between the 5th and 3rd).
  • A major interval (4 half steps between the 7th and 5th).

If we apply this principle to the C#maj7 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.
  • B# is the major seventh of C# because it is 4 half steps above the 5th.

Thus, this confirms that C# major seventh chord is defined by:

Root (C#) – Major Third (E#) – Perfect Fifth (G#) – Major Seventh (B#)

To sum up, in order to build the C#maj7 chord we need to add the major seventh (7th) to the C# major chord.
