3-9 Arpeggios Guide

3-9 Arpeggios Guide

One harmonic device that is frequently used by jazz musicians is the use of 3-9 arpeggios. In this lesson I will explain what 3-9 arpeggios are and how you can use them to take your jazz guitar improvisation to the next level.

Before diving into 3-9 arpeggios, a solid understanding of how normal arpeggios work first must be already established to fully undertand this lesson.

Like normal arpeggios, 3-9 arpeggios are four note patterns. But instead of starting of the root of the chord, 3-9 arpeggios start on the 3rd of the chord and finish on the 9th.

As essential and useful as the regular arpeggios are they can sometimes sound a little dull because you are only playing the notes in the chord. 3-9 arpeggios work well because they have most important notes of the chord (3rd and 7th) and the 9th which is a tasty extension.


Major 3-9 Arpeggios


The diagram below shows a normal C major 7 arpeggio followed by a 3-9 arpeggio. Play up and down each arpeggio a couple of times so that you can see and hear the difference between the two arpeggios. The difference between them is easier to hear in the contents of a C major 7th situation. Try using each arpeggio over a backing track or major 7th chord vamp to hear the difference.


3-9 arpeggio definition


You might have noticed that the 3-9 C major 7 arpeggio is also an E-7 arpeggio which brings me on to the next point. To quickly get the 3-9 arpeggio sound just think of the arpeggio a 3rd from the root. The table below shows how this substitution for each chord in the key of C and can be used as a reference


C Major 7th 3-9 = E-7 Arpeggio

C Dominant 7 3-9 = E-7b5 Arpeggio

C Minor 7 3-9 = Ebmaj7 Arpeggio

C Minor 7b5 3- 9 = Eb Minor Major 7 Arpeggio


The next example shows a 3-9 Major 7th arpeggio lick using a common jazz rhythm pattern.

Dominant 7 3-9 Arpeggios


The next chord type to look at applying 3-9 arpeggios over is the dominant 7th chord. To get the dominant 3-9 arpeggio sound, think of the minor 7b5 arpeggio a minor third up from the root of the chord.

The diagram below shows a 3-9 dominant 7th arpeggio followed by a lick that starts with a descending dominant 7th 3-9 arpeggio in a higher octave.

Minor 7 3-9 Arpeggios


One great jazz guitarist that used 3-9 arpeggios to help define his sound was the great Wes Montgomery, who particularly like to used them over minor 7th chords.

To get the 3-9 arpeggio sound over minor 7th chords just think of the relative major arpeggio which in this example is Eb. The diagram below shows a one octave fingering for a 3-9 arpeggio followed by a Wes-esc lick using a descending 3-9 arpeggio.

Minor 7b5 3-9 Arpeggios


To conclude the 3-9 arpeggio study for each chord type I have written out a one octave fingering for a minor 7b5 3-9 arpeggio which is also an Eb-major 7th arpeggio. The Locrian scale contains a flattend 9th instead of a natural 9th so you can use either.

But I personally prefer the sound of the natural 9th which is why I have included it in this article. After the one octave arpeggio fingering there is a lick using major 3rds found within the apreggio.

Connecting 3-9 Arpeggios


Now that you know how to apply 3-9 arpeggios over each chord type let’s look at how to connect them in two common progressions.

The most common chord progression in jazz music is the ii-V-I and the next example shows how to apply 3-9 arpeggios over a ii-V-I in the key of C.

Practice running these arpeggios up and down to see what kind of melodies you can come up with. To voice 3-9 arpeggios, try using other jazz soloing techniques such as enclosures and chromatic approach tones. The next lick demonstrates how you can use enclosures to voice lead 3-9 arpeggios in a ii-V-I situation.

Like four note groupings and normal arpeggios, 3-9 arpeggios are a great device to use over harmonically dense progressions such as the rhythm changes. The following example shows how you can connect 3-9 arpeggios with dominant 7b9 arpeggios over the I VI II V progression.

As with any new lick, scale, or arpeggio you learn practice 3-9 arpeggios in all 12 keys and in different positions across the guitar neck. Also practice applying 3-9 arpeggios over the progressions and tunes that you are working on too. What are your favorite ways to practice 3-9 arpeggios?

Good stuff, I'm sure you know that sweeping the 3rd, 5th, 7th across strings then picking the 9th is a common lick.

Also back sweeping the 7th, 5th. 3rd across strings and then picking the 9th is a common lick.

Yeah, that's a great classic lick I was going to include but for some reason didn't! Thanks for pointing it out.

Thank you Tony!

Hey Jamie! How do we apply the 3-9 arpeggio for chord melody without backing track?

Do we first play the actual chord e.g. C Minor 7 or root note C, and then 3-9 = Ebmaj7 Arpeggio? Or perhaps end with actual chord e.g. C Minor 7 or root note C?

What is the recommended approach?

What's a "vamp?"

It would be nice if you could show a chord-shape graph with each riff. I'm having trouble memorizing the various chords! I appreciate and use your instruction often! Merry Christmas 2014!!
