The C Chord Group

The C Chord

Here’s how to form the open C chord:

  1. Place your 3rd finger on the 3rd fret of the A string
  2. Place your 2nd finger on the 2nd fret of the D string
  3. Leave the G string open
  4. Place your 1st finger on the 1st fret of the B string
  5. Leave the high E string open


Strum all strings except the low E string:

The C Seventh Chord

The C seventh chord is often labeled as C7. In the open C chord we play the G string open, but with the C7 chord we’ll fret the 3rd fret of the G string with our 4th finger. This is the hardest chord we’ve learned so far!

As before, we’ll omit the low E string when we strum this chord:

C Major Seventh

The C major seventh is labeled as CM7 (capitol ‘M’ for major- a lower case ‘m’ would indicate minor). It’s easier than the regular C chord. All we have to do is remove our 1st finger from the first fret  and play the B string open.

  1. 3rd finger 3rd fret of the A
  2. 2nd finger 2nd fret of the D
  3. G, B, and high E are open

And once again, we’ll omit the low E string:
