Before tackling this course, you should be comfortable with all the material from Major 9th Chord

Let's now take a look at the minor 9th chords, which are once again built up from the minor 7th chord base. With minor 9th we have moved a long way from the original minor chord sound, so this chord has a very different usage to the basic minor, as we discover in this lesson.

Summary: Minor 9th

In the case of a minor 9th chord you simply take your minor triad (1st, b3rd, 5th) add the b7th (to create the m7 chord), and then the 9th. It is the addition of the 9th that changes the vibe of the chord to an even more relaxed sounding chord. Here is the formula applied to C major:

In Practice: Minor 9th Shape

To put this into practice on the guitar, below is two common Cm9 chord shapes. Notice the notes you are playing and try to call each one out in theoretical terms (i.e. the 1st, 5th etc...). Also notice that we don't necessarily include the 5th in the chord, that is something we will explain fully later on.

Dominant 9th Chords

For our final 9th chord we will be looking at the dominant family. Just as with the last two chords, we build the 7th chord first, then add the 9th. This is only the second dominant family chord we have made, so it's a very important chord that is the backbone of a lot of blues and funk playing!
