We’ve got a ton of awesome stuff to talk about so go to your piano and let’s get started!

The Barry Harris Harmonic Method

barry harrisThe Barry Harris harmonic method is one of the most unique ways of building chords there is in jazz piano.

Well, what exactly is that? How does Barry Harris think about it?

The Barry Harris harmony approach is a way of thinking about jazz chords and melodies based on specific 8-note scales.

Instead of using the usual 7-note scales, 8-note scales provide a way for you to discover new and exciting chord voicings. You can use these to unlock cool scale secrets that you can use to build any chord in any key.

In the next section, you will learn what is that magical scale that Barry Harris says everybody must know.

The First Two Chords You Need To Learn to Understand Barry Harris Harmony

Try this first: play a C6 chord:

Next, play a B diminished 7th chord:

The C6 and B diminished 7th chords have an interesting relationship. They tend to resolve into each other nicely!

Now, let’s say we combine the two chords to form a scale. How would that look like?

It will look like a scale that has the notes C, D, E, F, G, Ab, A, B:

Congratulations! You have discovered what Barry Harris calls a sixth diminished scale.

What’s A Sixth Diminished Scale?

The name “sixth diminished scale” is weird because music-theory-wise it’s not a diminished scale in the traditional sense.

It’s a scale that combines major and diminished together. This forms an amazing amount of harmonic possibilities that you can use to make songs super rich.

This scale got Barry Harris very excited about new possibilities. I hope you’ll be excited as well since it will make you sound awesome.

Barry Harris Wants You to Learn More About the Sixth Diminished Scale

barry harrisLets dig into this scale on an even deeper level now.

Sixth diminished scale appear in many styles of music. We even see it in the comprehensive lick breakdowns inside the Jazz Masters Method.

Playing little melodies from this scale creates really jazzy sounds.  In fact, you probably already know this scale by another name: the Major Bebop scale!

The sixth diminished scale and bebop scale can be used over any major chord. Check out this really awesome Major Bebop scale tutorial by Steve.

Now, that you understand the basics of the scale lets take it to the next level.

How to Explore the Sixth Diminished Scale

You start exploring the sixth diminished scale by simply playing it. Play the scale up, down, then play randomly. This is a similar manner to how you think of a Major Bebop scale.

Now, it’s time for you to make it a lot more interesting!

Get into exploring harmonies in the sixth diminished scale by playing it in thirds just like this:

CE – DF – EG – FAb – GA – AbB – AC – BD – CE, etc…

barry harris

The only odd one in this sequence is that major 2nd between G and A. However, that is necessary if you want to strictly play the scale in thirds in the proper sequence.

Once you’ve gotten the hang of playing the sixth diminished scale in thirds, go ahead and harmonize it as chords in this sequence:

barry harris

By playing the scale this way, you see how simplicity and sophistication can merge.

This concept of taking scales and turning them into chords is a skill that every serious piano player MUST master.

In fact, David Garfield has a whole system where he teaches how to turn scales into great sounding chord voicings in the Jazz Improvisation Super System.

If you think about it in a more sophisticated and hip manner, you end up having C6, Ddim7, C6/E, Fdim7 – C6/G – Abdim7 – Am7 – Bdim7

As you can see in the chart above, each chord resolves nicely to the next one.

Sounds complicated? There is a simpler way of thinking about it.

barry harrisWhen you harmonize the sixth diminished scale, you’re actually playing just two chords (a I6 and iidim7) and their inversions!

It so happens that they resolve nicely into each other!

Isn’t that just mind-blowing? It truly is!

How to Find Dominant Chords in a Diminished Chord

barry harrisOne of the most interesting things about harmonizing the sixth diminished scale is that you’ll discover a great number of dominant chords in it.

Now, what does that mean for you?

Remember that dominant chords always tend to act as V chords for particular keys.

Since you can get a lot of dominant chords out of the sixth diminished scale, this means that the harmonized sixth diminished scale will give tons of ways to change from one key to another in a really smooth way!

If you can easily change keys, you get to make really interesting music that will just be astonishing for your audience!

Now, do you remember when you played that sequence of 6 and dim7 chords? Just take a look at one of those diminished chords:

barry harris

Because those diminished 7th chords are symmetrical, all four diminished chords are actually the same chord!

However, that one diminished chord can yield four dominant 7th chords!

Here’s how you actually do it: Play a diminished chord with your right hand and then with your left hand play any note that is a half step below one of the notes of your diminished chord.

Here’s an example:

barry harris

That left hand chord becomes the root note of your dominant 7th(b9) chord!

How to Change Keys with the Harmonized Sixth Diminished Scale

barry harrisBecause you get the same diminished 7th chord every time with your harmonized sixth diminished scale, you get to have four dominant chords.

Let’s put this into practice: Let’s try a ii – V in the key of C:

barry harris

In the example above, you played a Dm7(9) then a G7(b9) chord consisting of a G for the left hand bass and an Fdim7 for the right hand.

In this case, you would expect a Cmaj7 to come up in the next bar as shown above.

What if you use a root note other than G over that diminished 7th chord? Use Bb this time:

barry harris

All of a sudden, you have a V chord that leads to the key of Eb!

Now try Db this time as your bass note over the Fdim7 chord. You can now go to the key of Gb:

barry harris

What about using an E as the bass? This time you can now go to the key of A:

barry harris

Again, to use this technique properly, use the notes a half step below the notes of your diminished chord as bass.

How to Find More Dominant 7th Chords Inside the Sixth Diminished Scale

barry harrisRemember how you played the sixth diminished chord in C and you found a C6 chord?

What if I tell you we can get four more dominant 7ths out of that with a few changes?

You want to know how? If you’ve read this far, I guess you want to know!

Here’s how to do it: You can voice lead effectively from a C6 chord to a C7(b9) chord by moving the A up to Bb and then add a Db before the E.

If you do this correctly, you should have a Gdim7 with your right hand.

As you have seen earlier, by simply changing the bass note, you can get four different dominant 7th chords out of that:

From those dominant 7th chords, you can effectively move from one key to another:

Being set free like this unlocks a great number of possibilities!

How To Best Practice Chords To Master Barry Harris Harmony

barry harrisThe best way to get a hang of the tips described earlier, it’s best to use what’s called a drop 2 chord voicing when going over the sixth diminished scale.

Drop 2 voicings are a great way to make your chords sound more open.

To understand how to form a drop 2 voicing, follow these steps:

1. Play any four-note chord in its first inversion. Use C6 for now so you’ll have EGAC:

barry harris

2. Drop the second highest note (A) an octave lower. For your C6 chord, you now should have AEGC

barry harris

Now that you know how to play a drop 2 chord voicing, harmonize the C sixth diminished scale using drop 2 chords:

barry harris

To get the most benefit out of this exercise, practice the sixth diminished scale in all 12 keys in drop 2 chords.

In this way, you’ll get a hang of how to harmonize and play chords just like Barry Harris.

Not only that, you now will be able to unlock various possibilities for playing music.

More freedom means more fun and more possibilities to mesmerize your audience.

This doesn’t mean you can stop. Being complacent will be the death of your musical journey.
