The C# minor chord (C#m) is built from a root note (C#), a minor third (E), and perfect fifth (G#):
- Type: minor triad.
- Formule: 1 ♭3 5.
- Music notes: C# (1) E (♭3) G# (5).
- Chords to play with: iv (F#m) y v (G#m).
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):
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.
C#m Guitar Chord
The C#m chord guitar has the following shape on the fretboard:
Let’s analyze in detail this chord diagram above to make sure that we understand how to play the C#m 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 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 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:
X 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).
⚠️ Important: it is not mandatory to memorize all this information to play the C#m chord on guitar. But it is highly recommended to know it in order to understand the musical theory behind each chord.
