Modes Part IV – Application

Modes Part IV

Applying modes to chords and chord progressions

Parallel

A parallel approach to chords and chord progressions is probably the best place to start, although, in the long run, this approach is more applicable to jazz and country-style playing than it is to rock or blues-style playing. Players of jazz and country tend to take things one chord at a time, utilizing different scales for each chord in a chord progression. Rock and blues players, on the other hand, tend to utilize one scale that fits the entire chord progression.

Be that as it may, it is important to have a thorough understanding of which chord types can be constructed from each of the modes.

Chords

Knowing which chord types can be constructed from each mode will help you to apply the modes in an actual playing situation. Let’s say for instance that you encounter a Bmin7 chord. According to the chord chart, three different modes can be associated with a min7 chord, Dorian, Phrygian and Aeolian. This means that for Bmin7, you could play the B Dorian mode, the B Phrygian mode, the B Aeolian mode, or any combination of the three possibilities.

There is an entire universe of harmonic and melodic possibilities waiting to be discovered within the modes of the major scale. This chart is only a place to start.

A great majority of the popular songs that you are likely to encounter have been written around modal chord progressions. In order to understand this modal structure, we have to take a look at the chord scale.

Just like modes, the secret to using the chord scale is which chord you resolve the progression to. (which chord the progression seems to come to rest on)

Below is a set of progressions using only the chords of the chord scale. Each progression, in turn, resolves to a different chord from the chord scale.

I – IV – V – I

ii – iii – IV – I – ii

iii – ii – vi – IV – iii

IV – vi -V – iii – IV

V – IV – I – V

vi – V – IV – V – vi

You will, undoubtedly, notice that I have failed to include the vii chord in any of these progressions. The vii chord is a difficult chord to use, and practically impossible to resolve a chord progression to. But that doesn’t mean that you should just forget about diminished chords. Have a listen to the intro to Jimi Hendrix’s Purple Haze, and you will hear a very effective use of the diminished sound.

So, what does this chord scale stuff have to do with modes?

It’s really quite simple. All you have to do is match the appropriate mode to the chord that the progression resolves to and you have it made in the shade. Just remember:

chord number = mode number

If the progression resolves to the I chord, the best mode to use is Ionian from the same root as the I chord.

For example, a I – IV – V – I progression starting with C would be:

CMaj – FMaj – GMaj – CMaj

The progression resolves to I, and the I chord is CMaj. Therefore, the best mode would be C Ionian.

If we do the same thing with a iii – ii – vi – IV – iii progression starting with C, we get:

Cmin – Bbmin – Fmin – DbMaj – Cmin

The progression resolves to iii, and the iii chord is Cmin. So the best mode to use is C Phrygian.

The hardest part of all this is to identify the chord of resolution as belonging to the chord scale. This is why you have to know the order of the chord types and how they are arranged via whole-step and half-step.

Let’s say, for example, that you encounter a repeating pattern of CMaj – BbMaj – CMaj and are expected to solo over those chords. By virtue of repetition, it’s a good bet that CMaj is the chord of resolution. The only thing left is to figure out which scale to use.

Chord scale:

 

I ii iii IV V vi vii VIII
w w h w w w h
Maj min min Maj Maj min dim Maj

 

There’s only one place within the chord scale that has consecutive major chords, and those two chords just happen to be a whole step apart. So, the CMaj is V, and the BbMaj is IV. Since the CMaj is home base, and it’s functioning as V, the best scale choice is C Mixolydian. (V chord = 5th mode)

But, if we change the CMaj to Cmin, an interesting thing happens.

Progression:

 

Cmin – BbMaj – Cmin

Chord scale:

 

I ii iii IV V vi vii VIII
w w h w w w h
Maj min min Maj Maj min dim Maj

 

Now we have a progression that could fit into two places within our chord scale:

 

ii – I – ii or vi – V – vi

That means that you could use either C Dorian (2nd mode), C Aeolian (6th mode) or both! The choice is your’s, but you would do well to consider which combination sounds most appropriate for the situation. You might find that the bass player or the piano player are using the Dorian mode for fills and/or chord extensions underneath your solo. If you play the Aeolian mode over the top of this, the results might not be quite what you expected. You’ve got to use your ears!

Sooner than later, you’re going to run into a progression that doesn’t quite fit our chord scale. There are many variations on, and extensions to this basic structure that have developed over time, but that is beyond the scope of this lesson. The best thing that you can do is to pick up some books on chords and chord progressions. There is a wealth of information available on this subject.

Two books that I highly recommend are:

Also, when it comes to rock music, often times, power chords (no 3rd) are used in place of major and minor chords (diminished too). In that case, the only thing you have to go by is the whole-steps and half-steps. This can make thing more difficult, but it also opens up greater possibilities for using more than one scale in your solo.

 

Below, are two MIDI files that are built around the concepts of derivative and parallel:

The Derivative file starts with C Ionian, then cycles through D Dorian, E Phrygian, F Lydian, G Mixolydian, A Aeolian and ends with B Locrian.

The Parallel file also starts with C Ionian but then cycles through C Dorian, C Phrygian, C Lydian, C Mixolydian, C Aeolian, and, finally, C Locrian.

I’ve tried to make each modal shift as distinct as possible, so that there is no confusion as to when to change modes. It’s up to you to make sure that you have the modes learned well enough that you are not fumbling around for the correct notes.

Listen to each file all the way through first and familiarize yourself with the modal shifts. (you’ll hear them!) Then, practice soloing over each progression:

Parallel

I would advise you to spend a lot of time with this lesson on modes. There is a lifetime of learning and understanding contained within these four pages. If you give it a cursory glance, your knowledge of modes will be cursory. Don’t assume anything. Explore the possibilities.

Along with your study of these pages, I recommend that you purchase these two resources:

  • Modes: No More Mystery by Frank Gambale. In this video, Frank demonstrates how to construct modal chord progressions, and then solos over each progression with the appropriate mode. If you are not familiar with Franks style, let me just say that this dude can really play! (Forrest: There are a zillion versions of this. Which one do I link in? -Dawn)
  • The Advancing guitarist: Applying Guitar Concepts and Techniques by Mick Goodrick in paperback. This book takes the same concepts provided in this lesson and shows you how to expand these concepts into other scales. This book will truly open up the fingerboard for you!
