Guitar Lesson
Pentamodal Idea

Bye Paul Tauterouff

Note: Prior knowledge of the five Minor Pentatonic box patterns and the 7 modal shapes is helpful for understanding this lesson, but not absolutely necessary.

Objective: To help guitarists already familiar with the pentatonic scale to learn and utilize the modes in their lead guitar playing.

As a guitarist, I am primarily self-taught and didn’t have any formal music theory training in the early stages of my playing. The first scales that I learned were the five positions or box patterns of the minor pentatonic scale. I wrote the diagrams out by hand, and would play (and draw) them constantly.

When I was first exposed to the seven modes of the major scale, I did the same thing; sketched the fretboard diagrams, studied how the shapes fit together, etc. Even after I had the modal shapes memorized, I was still having a difficult time actually applying them to my lead playing. Seven shapes just seemed like too many after becoming so accustomed to the five box patterns of the pentatonic scale.

Then I came up with an idea: What if I divided the modes of the major scale up into 5 scale chunks, based on the five Minor Pentatonic box patterns that I was already comfortable with? This way I would only have to add a couple of new notes to each of the 5 pentatonic boxes! For lack of a better name, I’ve decided to call this the Pentamodal Idea.

To demonstrate, let’s work out an example for a scale which is commonly used in rock guitar lead playing - the 6 th mode of the Major Scale, Aeolian mode (a.k.a. the Natural Minor scale). The following examples are in the key of A minor.

Here is our 1 st Pentamodal shape, Aeolian Mode:

Aeolian Mode w/ A Minor Pentatonic box 1 notes circled

We will skip Locrian, the mode that would normally follow Aeolian, since its first note (B at the 7 th fret of the low E string) does not align with our A Minor Pentatonic scale box patterns.

This brings us to Pentamodal Pattern #2, Ionian Mode:

Ionian Mode w/ A Minor Pentatonic box 2 notes circled

Note : Keep in mind that even though we may have skipped over the Locrian Mode, its notes are still available for us to use in our soloing via patterns 1 and 2, we just aren’t thinking of it as its own individual shape or box pattern.

Continuing in order, Pattern #3 consists of the Dorianshape:

Dorian Mode w/ A Minor Pentatonic box 3 notes circled

Next is Pattern #4, which includes the Phrygian mode:

Phrygian Mode w/ A Minor Pentatonic box 4 notes circled

We will skip the mode that would normally follow Phrygian, (Lydian) because its first note does not align with the Minor Pentatonic scale box pattern in our A Aeolian-based example.

This brings us to our 5th and final pattern, using the Mixolydian mode:

Key Points:

  1. Remember, we’re still playing all of the notes of the seven modes, we’ve just chosen to break them up into 5 box patterns – like our minor pentatonic scales.
  1. The above patterns will also work for a C Ionian (Major) root, since it is the relative major of A Aeolian Mode.
  1. Depending on which mode we choose to be our #1 (root) or parent scale, different modes may be skipped over. For example, if A Dorian minor was our #1 scale, we would skip Phrygian (at B, the 7 th fret of the low E string) and Lydian would be our #2 shape, at the 8 th fret (the C note).
  1. This is a “quick-and-dirty” method for assimilating the modes into your playing. Once you become familiar with using these shapes, I highly recommend also working out and memorizing the three note-per-string patterns for the modes. Box patterns are great for breaking ideas into small, easily digestible pieces, but you don’t want to be limited by them either.

I hope this lesson has helped you to begin to implement modal sounds into your guitar playing - have fun!
