How to Build Minor 9th Chords

In today’s theory lesson we’ll be looking at how you build m9 chords, as well as 8 commonly used fingerings for these chords that you can take into the practice and bring into your playing and songwriting.

The m9 chord comes from the aeolian mode, as it uses the 1st, b3rd, 5th, b7th and 9th notes of the aeolian mode in it’s construction.

Here is how you would build a Cm9 chord from the C aeolian mode.

Notice how the numbers of the C aeolian mode are used to spell the numbers of the Cm9 chord, 1-b3-5-b7-9, as this is the interval pattern needed to build any m9 chord, regardless of key.

So, the m9 chord is built by taking the Root, b3rd, 5th, b7th and 9th of the related Aeolian Mode.

Test Your Theory Knowledge

To help get this formula under your fingers and into your theory chops, you can write out all 12 different m9 chords, such as C Eb G Bb D for Cm9, and post them in the comments section of this thread.

I’ll be glad to check your work and help with any questions you have regarding this lesson on building m9th chords.

m9 Chord Shapes

To keep things practical as well as theoretical, here are 8 different shapes for Cm9 that you can take into your guitar playing.

Each of these shapes is commonly used and if you have even a few of them under your fingers will allow you to easily bring these sounds into your playing regardless of the style or musical situation.

Since we only have four fingers, and we are dealing with 5-note spellings, a lot of the time we omit the 5th when playing m9 chords, such as the ones you see below that use R-b3-b7-9 in their construction.

Check out m9 chords from both a construction and practical application.

These chords will pop up from time to time, or a lot if you play blues, jazz or fusion, and so it’s a good idea to have a mental and physical understanding of these common chords.
