9th Chords Made Easy

9th Chords Made Easy

As many of you readers begin to dig deeper into learning jazz guitar harmony and voicings, you’ll undoubtedly come across various 9th chords, Maj9, m9, 9 etc., in your jazz-guitar explorations.

Since these chords pop up time and again, it is important to have a variety of 9th chords under your fingers so that you can bring them into your comping, chord melody and chord soloing ideas when needed. But this doesn’t mean you have to learn a bunch of new chords. You can use previous knowledge to build great-sounding and authentic jazzy 9th chords.

In this lesson, we’ll be looking at how you can use “rootless” 9th chords to expand your jazz-guitar chord vocabulary without having to learn any new shapes, simply adapting four-note chords you already have under your fingers to a new musical situation.


Building 9th Chords with Common Voicings

To begin, let’s take a look at four common jazz chords with their 1357 and rootless 9th-chord voicings. Notice that each chord pair shares three notes in common: the 3-5-7 of each chord, but that in the second voicing the 9th has replaced the root, which is why we call them “rootless” 9th chords, as they contain no root in the voicing.

To get you started, here’s a quick reference for the four chords used below.

• Maj7 – m7 from the 3rd

• 7 – m7b5 from the 3rd

• m7 – Maj7 from the 3rd

• mMaj7 – Maj7#5 from the 3rd.

This means that if you see a Dm7 and you want to make it Dm9, you simply play Fmaj7, a Maj7 chord starting on the 3rd of Dm7. Try this out with each of the following chords, Maj7-7-m7-mMaj7, using the quick guide above as a reference, through all 12 keys and with as many voicings for each 9th as you can come up with.


Major ii V I with 9th Chords

Here are two examples of how you can apply rootless 9th chords to a Major Key ii V I progression, one using Drop 2 and one using Drop 3 chord voicings. As a quick reference, here are the three normal chords, 1357, next to the related rootless 9th chords. If you can memorize these formulas, you will be able to quickly and easily use these chords in any jam or gig you’re on.

• m7 – Maj7 from 3rd

• 7 – m7b5 from 3rd

• Maj7 – m7 from 3rd.

Try these chords out in all 12 keys, both all Drop 2 and Drop 3, then come up with your own rootless 9th chords and bring them into your Major ii V I progressions as you explore this concept further in the woodshed.

Minor ii V I with 9th Chords

To help get you started in the minor-key area, here is an example of a minor ii-V-I chord progression using both Drop 2 and Drop 3 rootless 9th chords. For the m7b5, we don’t normally include a 9th with that voicing, and so you will notice that I used a plain, 1357 chord in those instances. For the other two chords, G7b9 and CmMaj7, I used a Bdim7 over G7b9, producing a rootless 7b9 chord, and an Ebmaj7#5 over CmMaj7, producing a rootless mMaj9 chord.

As a quick guide, here are the three chords and their related 9th versions:

• m7b5 – stays as is

• 7b9 – dim7 from the 3rd

• mMaj7 – Maj7#5 from the 3rd.

Check out the example below, taking it to all 12 keys if possible, and then build your own 9th voicings for minor ii V I progressions using the rules given above.

2. Play the rootless 9th chord for any voicing you are working on and sing the root below the chord.

3. Take a tune you are working on and learn all of the chords as rootless 9th voicings, using the above lesson as a guide to find each 9th chord in the tune.

4. Practice any 9th chord that you learn with a number of different jazz guitar chords such as Drop 2 Chords, Drop 3 Chords and Drop 2 and 4 Chords.

5. Practice arpeggiating each of the rootless 9th chords in the above examples and begin to bring this concept into your soloing ideas as well.
