So now you have an overview of the basic drop2 voicings from the previous lesson: Jazz Chord Essential Part 1.
Here’s a short video on how I might use chords in a solo on a blues in C.
As you can probably hear I am not only using the chords in their basic form, but I am using different versions of the same type of chord to make simple melodies that then make up the solo. In order to expand the drop2 voicings from the last lesson and build other skills to play something like this we need to work on a few things:
Adding extensions to chords
Let’s look at how we can add more colors to the voicings we already have and a few tricks that will help you use and expand what you already know.
So far we’ve been concerned with the basic chords so Am7 was simply root, third, fifth and seventh, but as I explained in the first lesson you can use Am9 or Am11 instead of Am7. Instead of making 5 or more note voicings we can use these rules to exapand the sounds:
- 9th (or b9 or #9) can replace the root
- 13th, b13th, b5, #5 can replace the 5th
- 6th can replace the 7th
- 4th or 2nd can replace the 3rd
This means that if we want to make an Am9 voicing you take the Am7 voicing and change A to B. You might notice that this means that you’ll be playing the notes B C E G which is a Cmaj7, so you can use Maj7 voicings to play minor 9 voicings. If you use the same approach to D7, you have D F# A C and that becomes E F# A C which is F#m7(b5). On Gmajor7 you have G B D F# and get A B D F# which is Bm7.
You’ll notice that I prefer just using the “category” Chord symbols Am7 even though I am playing the 9th. Think of it as part of the process of not having a one to one combination from chord symbol to voicing, something you probably already had to abandon with several ways to play a C or a G chord.

One way to vary the sound of cadences is to use an altered dominant. This almost only works when the dominant is in fact resolving to a I chord, but that is for another lesson on theory.
One observation that is handy is that if you play a D7(b9,b13) having substituted the root with b9 and the fifth with the b13 you have these notes: Eb F# Bb C which are exactly the same notes as Cm7(b5) (or Ebm6) . So that gives us this set of II V I Cadences:

Of course these are just examples on how you can change the voicings to get other extensions.
Melodies in the voicings
When I play chords behind a soloist I am often playing melodies with the top voice of the chords to make the harmony more logical to the listener. I also sometimes play parts of a solo in chords. One way to develop the skills needed for this is to use chords to play a melody. The simplest possible melody is probably a scale on, so let’s do a few exercises with that:

As you can see there are a few notes in the G major scale that are tricky to harmonize, and there are several options on how to deal with them. The note C is never going to sound like a Gmaj7 chord so I chose to play an Am7 there. I could have substituted it with a C# and used a Gmaj7(#11).
Let’s make a similar exercise using a turnaround: Am7 D7alt Gmaj7 E7alt. With this exercise I am just forcing myself to move up the neck in small steps, not really any system, even if it’s almost chromatic. I guess for all of these “melodic” voicing exercises the goal is to be able to make your own more than actually play mine!
