Pentatonic Scale Essentials Guitar Lesson

pentatonic scale

The pentatonic scale is one of the most popular guitar scales due to its simplicity and versatility. It’s called the pentatonic scale because there are only five notes in the scale, as opposed to the usual 7 notes in most others. “Penta” means five and “tonic” means notes. 

Pentatonic scales are widely used in a number of genres like rock, blues, country, pop and more. Guitar virtuosos like Stevie Ray Vaughan, Jimi Hendrix, Eric Clapton, and many others have all featured this scale in their blistering solos. If you're already familiar with the scale, make sure you know how to practice the different shapes here.

If you want to learn how to put this new scale to use, watch the lesson below on how to solo using a pentatonic major scale.

 

There Are Only Five Notes!

Pentatonic scales are derived from the major scale. The major scale is formed by playing a note, the root note, and then ascending to the next notes using a pattern of whole-steps and half-steps. 

A whole-step is when you go from one whole note or “tone”, to another. For example, when you go from an A note to a B, that’s a whole-step, or full-tone. But if you go from an A note to an A# note, that’s a half-step, or semi-tone. 

W = whole-step

h = half-step

Below is the magic formula for creating a major scale: 

W W h W W W 

Following the above rules, a C major scale looks like this:

1 - 2 -  3 - 4 - 5 -  6 - 7  (the order of each note from starting at the root. C is the 1st note, D is the 2nd note, etc.)

C - D - E - F - G - A - B  

  W   W   h   W   W   W   

 

How to Create the Pentatonic Major Scale

In order to turn this C major scale into a C major pentatonic scale, we must remove two notes. The formula for the major pentatonic scale is as follows:

1- 2 - 3 - 5 - 6 

The two notes that we must take out are the 4th and the 7th notes. In the C major scale, those notes are the F and the B because the F is the 4th note and the B is the 7th note in the scale.  After removing these notes, here is what we have:

C - D - E - G - A 

That’s the C Major pentatonic scale! And it looks like this on your guitar:

The black notes are the root notes, in this case the C note. 

Alright, so how do you make a minor pentatonic scale? 

For the minor pentatonic scale, there is a different formula. Check it out:

1 - b3 - 4 - 5 - b7

So apply this formula to the C major scale, which we know from earlier is this: 

C - D - E - F - G - A - B 

After applying the formula, what you get is this:

C - Eb - F - G - Bb

And this is what it looks like on a guitar:

The black notes are the root notes, in this case the C note.

A neat trick is that these scales can be moved up and down the neck. For example, if you look at Pattern 2, you’ll notice that the root note is on the 8th fret of the low E string. With this in mind, you can move that entire shape to different root notes and change the entire key you’re playing in. 

For example, if you take the shape from Pattern 2 and apply it to the 5th fret, you’ll be playing an A minor pentatonic, because the 5th fret of the low E string is an A note. You can do this for all of these patterns up and down the neck.

And there you have it, that’s the pentatonic scale! Good luck with it and have fun.
