How to Play the Open Position C Chord and CAGED C Shape
In the video lesson above, you learn how to play the C chord in open position, as well as how to turn it into a moveable C shape.
You might wonder, why a whole video on such a basic chord? Isn’t a chord box enough?
It’s not just about fretting the shape — it’s what you can and can’t do with it that matters. That’s what you explore in the lesson.
Once you can play it in context — switching to and from it in songs, strumming, picking, etc. — the next step is to turn it into a moveable C shape.
Below is an open-position C chord and its moveable version, taken from Chordacus. From low to high, the intervals are: root, 3rd, 5th, root, 3rd.
C chord extensions
To extend the C chord, we must understand both the theory behind chord construction and the possibilities offered by the C-shaped chord.
Here are some of the chords you can build from a C shape:
- C major (root, 3rd, 5th, root, 3rd)
- Csus2 (root, 2, 5, root)
- Cadd9 (root, 3, 5, 9)
- Csus4 (root, 4, 5, root)
- C7sus4 (root, 4, b7, root)
- C6 (root, 3, 6, root)
- C6/9 (root, 3, 6, 9)
- Cmaj7 (root, 3, 5, 7)
- C7 (root, 3, b7, root)
- C9 (root, 3, b7, 9)
- C7b9 (root, 3, b7, b9)
- C11 (root, b7, 9, 11)
To fully grasp and recognise these chords, you need real songs using them.
For example, Talking About a Revolution plays a Cadd9 with an open E string — Time of Your Life doesn’t.
To hear a Csus2 in a C shape, try Rewind by Paolo Nutini.
A Csus4 in open position appears in Angie by The Rolling Stones.
Kiss Me by Sixpence None The Richer offers a great example of Cmaj7 and C7 in open position.
Finally, a C-shaped E chord using the open E string can be found in Angels by Robbie Williams.
Building scales and arpeggios around the C chord/shape
There’s more you can do with the C shape than just build chords — it can also form the basis for arpeggios and scales.
We can turn it into a maj7 or dom7 arpeggio, a major pentatonic, or play modes like the major scale (Ionian), Lydian, and Mixolydian.
Below are all the intervals used to build these arpeggios and scales around the C-shaped chord.
If you can see all the intervals around the chord shape, you can play every one of these arpeggios and scales.

The Cm chord
The open-position Cm chord and shape are usually avoided by most guitar teachers and players — you’ll find it in very few tunes.
Being impossible to play in full, the Cm chord becomes the fork in the road for truly understanding the guitar fretboard.
