PART TWO - PLAYING THE CHORD CHANGESIn PART ONE we learned how to use a note or two over a short chord sequence: the ubiquitous, overused but necessary ii / V.* We selected our note(s) from a short list of pitches that sound consonant in relation to BOTH of the chords. We essentially ignored the harmonic "changes" as a first step towards improvising with confidence.
Now we are going to choose pathways that specifically indicate which chord we're improvising over at any given time. This is much easier than it sounds, because these particular chords - ii and V - are very closely related to one another. In fact, there's only ONE note that has to move (or change) when we toggle between these two harmonies!
* Don't worry about the meaning of ii and V if you don't get that yet. It will all become clear in a moment.
USING TARGET TONESRather than get into a theoretical explanation, let's get right to PLAYING what we'll call TARGET TONES. Instead of taking one or two notes through both chord changes (as we did previously) we're going to choose what note to "land on" when we get to each chord change. Let's use the one note that MUST shift when we move from back and forth between ii and V.
In the key of C, we will play the note C on the ii chord, the first chord in the repeating sequence. On the V chord, we'll play the note B.* That's it. Try this using the same backing track we used in PART ONE.
ii V in C
That works pretty well, doesn't it? If you got messed up and started playing the wrong note in relation to the chord, that sounded pretty sour, didn't it? Here's why:
Let's name and dissect these chords so we can see how the notes C and B relate to their respective harmonic contexts. In the key of C, the ii chord is D minor seventh (notated as D-7 or Dm7 or Dmin7). We call it a "ii chord" because D is the 2nd note of the major scale that starts on C. D-7 contains the notes D - F - A - C (root, minor 3rd, perfect 5th, minor 7th - ALL minor 7th chords have this structure).
The V chord likewise is constructed on the 5th note of the C major scale - G. It's called G dominant seventh (notated as G7). G7 contains the notes G - B - D - F (root, major third, perfect 5th, minor 7th - ALL dominant 7th chords have this structure).
SO - The note "C" is the minor 7th of the D-7 chord; and the note "B" is the major 3rd of the G7 chord. Take a look at the example below to confirm this (because I might be lying, you never know).
*Bb and Eb instrumentalists: you can easily transpose these notes by now, yes?
The first measure shows each full chord. I've dropped the root "G" down an octave to show you that the notes "D" and "F" are present in the middle of both chords. In measure two I've eliminated those "common tones" (and the irrelevant note "A"*). The arrows are showing you how the notes "C" and "B" relate to the roots - again, the "C" is the 7th of D-7; the "B" is the 3rd of G7. In the 3rd measure I've gotten rid of the root and put the "F" back into the mix. You'll see why that's important very soon. Finally, I've notated just the moving note that you experimented with a few paragraphs ago.
In a sense, then, this movement between "C" and "B" DEFINES the chord change! That's why they're called TARGET TONES. I have to confess that I told you a little white lie earlier. There is actually one other (very important) movement that defines the chord changes: the ROOT of each chord. If you move from the "D" on the D-7 to the "G" on the G7 that will give you a very clear sense of one chord changing to the other. I left this root motion out not because you can't use those notes, but because it is normally the job of the bass player to define the chord changes using root motion. Using the roots as the melody notes in your improvisation isn't wrong; it just might not be all that interesting.
*"A" is the perfect 5th of the D-7. It turns out that, because 5ths are present in almost all chord types, they don't help us to understand how the harmony works. Take this on faith for now, OK?
MORE TARGET TONES: 3rds and 7thsLet's take this one step further. I've hinted at the importance of the 3rds and 7ths of chords, so it's time to be more specific about this. To make this possible, we're going to use a longer sequence of chords (there's only so much you can get out of just ii and V in this regard). The chord progression is:
ii / V / I / VI In the key of C, which translates to D-7 / G7 / CM7 / A7.
Now we have a complete turnaround, having added two chord changes (I and VI) to the original progression. Let's skip the chatter for a moment and PLAY some TARGET TONES through this set of changes. Here's the melody to start with:
C / B F / E D / C#
ii V I VI in C
TIME OUT FOR A QUIET CHAT ABOUT 3rds and 7thsPut down your horn for a second because we need to have a quick harmony discussion. After the root, the most important notes in any chord are the 3rd and 7th. Why? Because those two notes establish the QUALITY of the chord, and therefore transmit a lot of essential information to you, the improviser. Have a look at the following:
- CM7 contains a MAJOR 3rd and MAJOR 7th
- C7 contains a MAJOR 3rd and a MINOR 7th
- C-7 contains a MINOR 3RD and a MINOR 7th
In case you misplaced it, here's that backing track for the turnaround:

USING CHORD TONESThere's no clearer way to "play the changes" than to literally play the chords AS a melody. You can do this in a variety of ways:
- Simply play all 4 notes in order from bottom to top: root, 3rd, 5th, 7th. (Ex. 1) Then do the same thing from top to bottom. (Ex. 2)
- Alternate directions; play one ascending and the next descending: UP root, 3rd, 5th, 7th DOWN: root, 7th, 5th, 3rd. (Ex. 3) Then do it descending/ascending with the same shapes. (Ex. 4)
- Incorporate the TARGET TONES by changing the order of the chord tones. One way to do it is: UP root, 3rd, 5th, 7th DOWN 3rd, root, 7th, 5th, UP 3rd, 5th, 7th, root, DOWN 3rd, root, 7th, 5th (Ex. 5)
- Change the ORDER of the chord tones to achieve more interesting melodic shapes, as in Ex. 6. Use the knowledge you acquired working with just 3rds and 7ths to guide you from one chord sound to the next.
ii V I VI in C You can get a lot of mileage out of this simple technique. The beboppers certainly did!
As always, you'll want to do this in all 12 keys. This 4 bar turnaround occurs, in various guises, in a huge number of standard tunes. Mastering it will go a long way towards helping you internalize the jazz tradition. Think of it as a springboard to the development of your own personal musical language.
