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 C# 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#)

Let’s analyze in detail this chord diagram above to make sure that we understand how to play the C# on guitar. To do that we will 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 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#  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 C# chord on guitar. But it is highly recommended to know it in order to understand the musical theory behind each chord.
