Jazz piano or other styles.
As an improvising pianist, we are constantly working to create interesting solos and improvisations. This involves a process of learning many tips and tricks over the years that we incorporate into our playing.
Here is a way to create very interesting improvisation lines over a dominant 7th chord. Dominant seventh chords are by far the most common quality of chord found in modern music. One reason is because the dominant seventh chord contains a tri-tone, a very unstable interval that wants to move and resolve. So, learning this improvisation trick will come in handy with many different songs and styles.
Let’s begin by talking about available tensions on dominant seventh chords. An available tension is a note that is not part of the chord, but can be played with the chord to create tension. Not all tensions are created equal. Some tensions add a little tension to the chord while others add a lot of tension. This is also very subjective because what is tense to your ears might not be tense to my ears at all!
Common available tensions for dominant seventh chords are: b9, 9, #9, #11, b13 and 13. Often, these tensions will be played together and there are many common tension groupings that I discuss in the Piano Chords bundle.
So, if we spell out the notes and tensions for a C7 chord, we get:
C7 chord tones:
- C-root
- E-third
- G-fifth
- Bb-flat seven
C7 chord tensions:
- Db-flat nine
- D-nine
- D#-sharp nine
- F#-sharp eleven
- Ab-flat thirteen
- A-thirteen
So that makes all of the chord tones and tensions: C-Db-D-D#-E-F#-G-Ab-A-Bb.
Only F and B are missing from the list. This means that on a dominant seventh chord, you can play virtually ANY note and it won’t sound all that bad. Of course, it is always important to use your ears and knowledge of harmony to create good lines.
Now that we know that almost any note goes for a C7 chord, we can use our quartals to create some interesting lines. For this example, I am going to use some basic rhythms. If you need help with your rhythm, I’d like to suggest that you check out my Mastering Rhythms DVD series.
I’m going to use quartals built starting on the #9, 3rd and #5 to create some interesting lines. Musicians often refer to the musical phrase as a ‘line’. “That player plays great lines.”

This is just one example of how to create an interesting and modern sound using quartals. These lines sound modern because they are built using quartals instead of tertial-based lines using chord tones or lines built from scales.
You can create dozens of interesting lines using quartals. Learn more about improvising using quartals on the new Quartal & Pentatonic Improvisation DVD.
