If you’ve been playing guitar for any length of time then you’ve probably heard the term “pentatonic” used in reference to scales. It’s a musical term that sounds a bit intimidating at first, but is really very simple to understand.
The prefix “penta” means five. We see the same prefix used in other words like pentagon (having five sides) and pentagram (a five pointed star.)
The musical term “tonic” refers to the first tone or keynote (the tone which identifies the scale.) The note C for example, is the tonic of the C major scale. When we put these two terms together we have the word “pentatonic” which refers to a five note scale based around the first tone, or keynote.
There are both Major and Minor Pentatonic Scales for Guitar. We can build either one by simply altering an existing seven tone scale. Here’s how it’s done using the C Major Scale…
C Major Scale:
C D E F G A B C
1 2 3 4 5 6 7 8
C Major Pentatonic:
C D E G A C
1 2 3 5 6 1
C Minor Pentatonic:
C Eb F G Bb C
1 b3 4 5 b7 1
It’s helpful to memorize the combination for each type of scale. This will enable you to play each scale anywhere on the neck from any keynote you choose.
Another way to learn and utilize scales is by memorizing a specific finger pattern. There are several patterns for each type of scale that I’ve shown above. These patterns are movable and can be used to create licks or riffs that you can use to play over chords.
1. The most common finger pattern for a Major Scale is:
Fret: 3 5 2 3 5 2 4 5
Finger: 2 4 1 2 4 1 3 4
String: 6 6 5 5 5 4 4 4
e||—|—-|—-|—-|——|—|-
b||—|—-|—-|—-|——|—|-
g||—|—-|—-|—–|—–|—|-
d||—|-1-|—-|-3-|-4-|—|-
a||—|-1-|-2-|—-|-4-|—|-
e||—|—-|-2–|—-|-4-|—|-

Root
The numbers on the fretboard represent your fingers. The scale starts on the 6th string with the 2nd finger on the the 3rd fret. This is the Root note (tonic) G.
Playing the pattern above from the 3rd fret will give you a G Major Scale:
G A B C D E F# G
1 2 3 4 5 6 7 8
2. A common finger pattern for a Major Pentatonic Scale is:
Fret: 3 5 2 5 2 5
Finger: 2 4 1 4 1 4
String: 6 6 5 5 4 4
e||—|—-|—-|—|—-|—|-
b||—|—-|—-|—|—-|—|-
g||—|—-|—-|—|—-|—|-
d||—|-1-|—-|—|-4-|—|-
a||—|-1-|—-|—|-4-|—|-
e||—|—-|-2-|—|-4-|—|-
R
Playing this pattern from the 3rd fret will give you a G Major Pentatonic Scale:
G A B D E G
1 2 3 5 6 1
3. A common finger pattern for a Minor Pentatonic Scale is:
Fret : 3 6 3 5 3 5
Finger: 1 4 1 3 1 3
String: 6 6 5 5 4 4
e||—|—|—-|—|—-|—-|-
b||—|—|—-|—|—-|—-|-
g||—|—|—-|—|—-|—-|-
d||—|—|-1-|—|-3-|—-|-
a||—|—|-1-|—|-3-|—-|-
e||—|—|-1-|—|—-|-4-|-
R
Playing this last pattern from the 3rd fret will give you a G Minor Pentatonic Scale:
G Bb C D F G
1 b3 4 5 b7 1
Each of the scales given above can also be played an octave higher. The fingering would change slightly, but the notes will be the same and you would remain in essentially the same position on the fretboard. See if you can figure it out for yourself by continuing to play the notes of each scale pattern up to the first string. Let the exercise test your knowledge of the fretboard.
Once you have that down, move the patterns by starting on the 6th string at a different fret. The note you begin with will determine the name of the scale you’re playing. Remember to keep the finger patterns consistant or they won’t sound right. Experiment and have some fun!
