The C minor 7 chord is a less commonly known chord when first learning to play guitar. You may also see this chord written as C min 7, Cm7, or C – 7 on sheet music.
In this lesson, we’ll go over some basic chord theory and then cover 8 ways to play a C minor 7 chord which you can start incorporating into your playing.
Grab your guitar and let’s get started!
C minor 7 chord theory intro
Every minor 7 chord is built upon the following four chord tones: 1, b3, 5, and b7. These chord tones can also be thought of as the scale degrees related to one minor scale.
For example, the C minor 7 chord has the chord tones C, Eb, G, and Bb. This is essentially a C minor chord with an added b7 chord tone.
Here is the formula for minor 7 chords below.
In contrast, Major 7 chords contain the chord tones 1, 3, 5, and 7. For example, C Major 7 chord would contain the chord tones C, E, G, and B. However, we will only be covering the different minor 7 chord variations in this lesson.
Now that you know what notes belong to the chord structure, let’s look at how to read the chord charts.
How to read the chord charts
For the charts below:
- The top horizontal line of the chord chart represents the high E string and the bottom horizontal line represents the low E string.
- The vertical lines separate each fret.
- The numbers in the blue dots tell you which fingers to use on the fretting hand.
- The letters on the right of the charts tell you what notes you are playing on each string.
- Circles on the left represent open strings.
- Red X means to avoid that string.

Wrapping up
All these chords were mostly in root position, meaning the root note is in the bass. However, you have even more variations if you use different chord inversions. This is when you play a chord with notes other than the root in the bass.
It’s good to know many possibilities of playing the same chord because you have more flexibility to move around the fretboard. Also, you can use different chord variations when you need a certain note at the top to help define a melody that you are playing over.
