Music Lesson: Exploring the Pentatonic Scale

Introduction

In the last lesson, we developed the idea of using the major scale as a tool for improvisation. While the major scale is very useful, it can also be quite limited. It's essential to quickly move on to the pentatonic scale, which is an extremely versatile scale used in various musical contexts.

What is the Pentatonic Scale?

The term "pentatonic" means five notes. This scale leaves out the fourth and seventh degrees of the scale, making it simpler and much more melodic. In the key of G, the pentatonic scale would include:

• 1 (G)
• 2 (A)
• 3 (B)
• 5 (D)
• 6 (E)

You can also think of it in terms of intervals:

• Tone
• Tone
• Tone and a half
• Tone
• Tone and a half

Tip: Getting the sound of this scale in your head is crucial for improving your musical ear. With this information, you can easily derive any pentatonic scale.

Example: Pentatonic Scale in C

For example, in the key of C, the pentatonic scale can be thought of as:

• Tone
• Tone
• Tone and a half
• Tone
• Tone and a half

Practice: Spend some time working out various pentatonic scales, and then try extending them to two octaves. It's not only useful to go up to two octaves but also to utilize all available notes within the first position.

Why are Pentatonic Scales Useful?

Pentatonic scales are particularly useful due to the notes that have been left out. The remaining notes fit together harmonically or melodically in any combination.

Piano Illustration

On the piano, we can illustrate this by playing:

• White notes: Represent the C major scale.
• Black notes: Represent the pentatonic scale.

Let's compare the sounds:

• First, play a bunch of white notes together...
• Now, play a bunch of black notes together...

The black notes harmonize nicely, while many of the white notes do not.

Fun Classroom Analogy

Imagine a classroom full of four-year-olds with xylophones. If they are given the full scale, the result is utter chaos. However, if you provide them with only the pentatonic scale, everything they play will harmonize, resulting in a much more pleasing sound.

Learning the Pentatonic Scale

Having learned how to construct pentatonic scales, the next step is to get your fingers to learn them.

Initial Position Practice

For example, with a D major pentatonic scale:

• Start on a convenient tonic note (open D) and play a single octave:
  • Fingering: Open, 1, 2, Open, 1, 3.

Keep going to the top of that position, then turn around and descend back to your starting point.

Exercise:

• This method allows you to present all available notes in the first position usefully and accessibly, contrasting with the classical approach that may leave certain notes unplayed.

More Scales

Try working out more scales in different keys. For example, here's the F major pentatonic:

• Start on F and end on F, playing from the top back to the bottom.

Practice: It takes a lot of time to memorize these scales. Use a numbered finger pattern to make it easier.

Example: E Major

• Fingering: 1, 2, 3, 1, 2, 4.

Playing Faster

The essential idea is that you should be able to play faster than you think, enabling you to execute the entire scale in a single bow. Practice this in easy keys such as G:

• Fingering: Open, 1, 2, Open, 1, 3, Open, 1, 3, Open, 2, 3, 4.

Mastering the Technique

Before you can master one technique, you must first master the previous one. You won't be able to think that fast regarding constructing the pentatonic scale until your fingers are familiar with it.

Extending Beyond First Position

The final piece of mastering pentatonic scales involves playing them outside the first position.

Transitioning to Third Position

Starting with the G major pentatonic scale, begin at the root but now in the third position.

• Fingering: 1, 2, 3, 1, 2, 4.

Extend it up and down and end where you started. This allows you to play the same pattern in any key.

For example, let's move to the key of F sharp or A flat:

• The beauty of this system is its versatility across the entire neck, using the same finger pattern regardless of key.

Note Freedom

In challenging keys like F sharp or C sharp, you can ascend the neck using the same pattern without knowing the specific notes. This approach ensures that everything you play will sound great as long as you're following the right pattern.

Closing Exercise: Mind the Gap

Let's take a look at a tune called Mind the Gap. This piece is based on the pentatonic scale.

• Listen closely while I play an improvisation over the same tune, using the G major scale, the G major pentatonic scale, and transitioning between positions.
