Pentatonic Scales

What Are Pentatonic Scales?

Pentatonic scales are frequently used in music all over the world : Eastern, European, Mediterranean, African, Amerindian, Oceania. The word "pentatonic" comes from the Greek word "pente" meaning five and "tonic" meaning tone. They are considered earlier than heptatonic scales. They are divided in two categories :

Containing semitones (hemitonic)
Without semitones (anhemitonic)

There are many pentatonic scales, the best known are the major pentatonic scale and the minor pentatonic scale (also known as "the relative minor pentatonic"). They do not have semitones (anhemitonic). These two scales are very important for jazz blues guitar players and improvisers.

The Five Modes Of The Major Pentatonic Scale

Each degree of the major pentatonic scale (which is what we are interested in) can provide a tonic for a mode. There are five modes :

Mode I (major pentatonic) that consists of the first, second, major third, perfect fifth and sixth.
Mode II aka Egyptian pentatonic scale or suspended pentatonic (no third, suspended scale) : 1 - 2 - 4 - 5 - b7
Mode III (Blues minor) aka Man Gong scale (minor) : 1 - b3 - 4 - b6 - b7
Mode IV (Blues Major) aka Ritusen scale (no third, suspended scale) : 1 - 2 - 4 - 5 - 6
Mode V (minor pentatonic) that contains the same five notes as the major pentatonic scale, but its tonic (first note of the scale) is three semitones below the tonic of the major pentatonic scale : 1 - b3 - 4 - 5 - b7

Relative Minor

What's the relative minor pentatonic scale ?

For every major scale there is a relative minor scale and for every minor scale there is a relative major.

Relative minor scales begin on the sixth degrees of major scales.
Relative major scales begin on the third degree of minor scales.

These two rules work for all the scales and chords.

Let's take an example with the C major pentatonic (C - D - E - G - A). It has the same notes as the A minor pentatonic (A - C - D - E - G). The sixth degree of the major pentatonic scale is the tonic of the minor pentatonic scale.

Now another example with the G minor pentatonic scale (G-Bb-C-D-F). The relative major pentatonic scale start on the third degree of G minor. Thus giving the Bb pentatonic scale (Bb-C-D-F-G).

Rare Pentatonic Scales

Now that we have talked about the most played pentatonic scales, here are some other pentatonic scales rarely used, some of them have altered notes :

These following are from the major scale :

Dorian pentatonic scale : 1 - 2 - b3 - 5 - 6. This scale is sometimes referred to as "Kumoï".
Phrygian pentatonic scale aka Dorian b2 pentatonic : 1 - b2 - 4 - 5 - b7
Lydian pentatonic scale : 1 - 2 - 3 - #4 - 6 (major pentatonic scale with a sharp eleventh instead of the perfect fifth). There are two other versions : 1 - 3 - #4 - 6 - 7 and 1 - 3 - #4 - 5 - 6.
Mixolydian pentatonic scale or dominant pentatonic scale : 1 - 2 - 3 - 5 - b7 (mixolydian mode without the sixth and the fourth).
