If you are on this page it's likely you already know how to play the standard C major chord. It's one of the first shapes that beginners learn (even if it's not the easiest one) as many songs contain the C major chord in the progression.
In this article, I want to show you some C chord variations, that will help you advance your chord theory knowledge.
Depending on the chord tones you'll add or remove, the quality of the chord could change, and in the following, we're going to deepen this important concept.
The C Major Chord - Standard Shape
Let's start analyzing the most common form for the C major chord. A major chord is composed of the root, the 3rd and the 5th note of its corresponding major scale.
In the case of C, the scale is C, D, E, F, G, A, B and C. The 3rd is E, and the 5th is G. So the C major chord is C, E and G.
The most used chord shapes often use open strings, because they allow easier fingerings and better sounds.
The C major chord is no exception, so, as you can see in the picture, the G and the high E strings are left free to ring.
The lowest E string is muted because we want to have the root of the chord, C, as the lowest note.
C Major Chord Variations
Now we're going to press or release some frets, trying to keep the left hand in the same position. Let's analyze the resulting chords.
For this analysis, I used my reverse chord finder tool, be sure to experiment with it if you want to understand better chord construction.
C Major Chord - Standard Shape
Ok, this is the standard C major chord voicing that we all should know.
If you look at the diagram below, you'll notice that notes C and E are present twice on different frets. This happens frequently on guitar chords.
C Major Chord - Variation 1
The first variation we can introduce is by placing your pinkie on the 3rd fret of the E high string, which is a G.
We still have the same notes C, E and G, but the sound is a little different.
C Major Chord - Variation 2
In this voicing, we play the G on the low E string (with the pinkie). Now we have a G as the lowest note of the chord, but the chord is still a C major, because the notes on the table are still C, E a and G.
The correct way to name this chord is C/G, which means a C major chord with a G on the bass.
C Major Add9 Chord
If we place the pinkie on fret 3rd of the B string, we'll get a D. D is the 2nd note of the C major scales, so the notes in this chord are: C, E, G and D. We name this chord C add9.
Why add9? Because D is the 2nd note in the scale, and if we go one octave higher, it's the 9th (count to verify). So it's a C major chord plus (add) a 9th.
C Major Dominant 7
We move again our pinkie, this time we place it on the 3rd fret of the G string, which is a B flat. B is the 7th note of the C major scale,
Bb is then b7 (one half-step down). We have 1 (C), 3 (E), G (5) and Bb (b7) which is the formula of the C dominant seventh chord.
Notice that the G (5) is not present in this voicing. It's correct, the 5th is often dropped because it does not bring too much harmonic information and can be discarded in favor of an easier fingering.
C Major 7th Chord
This is an easy voicing: let the 3 higher strings ring open!
We have a new note here, B, which, as stated before, is the 7th note of the major scale. The formula is 1 (C), 3 (E), 5 (G) and 7 (B), which turns out to be a C major seventh chord.
C Major 6th Chord
This fingering includes the note A. If we count from C to A, we get 6.
Indeed, this is a C major 6 chord: C (1), E (3), G (5), A (6).
C9 Dominant Chord
If we add a 2nd (D) to the dominant seventh chord, we get a C dominant 9 chord.
C (1), E (3), G (5), Bb (7), D (9).
Notice that the 5th is dropped also in this voicing.
C 6/9 Chord
We now can combine the 6th and the 9th: C (1), E (3), G (5), A (6), D (9), to get a C 6/9 chord, used often in Gipsy Jazz.
C Augmented Chord
The 5th can be dropped, as seen before, or can be raised or lowered. If we raise the 5th (G) by one half-step (G#), we get the formula for a C augmented chord: 1 (C), 3 (E), 5# (#G).
C Sus2 Chord
Ok, now we can drop the 3rd note in the chord, to get a chord quality that is not major neither minor. Here's the C suspended 2 chord1 (C), 2 (D), and 5 (G).
C Sus4 Chord
Same as before, but this time we use the 4th instead of the 2nd: 1 (C), 4 (F), and 5 (G) are the notes that create a C sus4 chord.
