Major Pentatonic Scales work in a variety of situations, but are most often used on Dominant 7- or Major-type Blues progressions, in Country over Major chords or in Rock over Power chords. They have a very distinctive ‘happy’ vibe so probably won’t be your first choice if you are searching for a hard-edged, aggressive solo.

It is also worth noting that many vocal pop melodies are created with the Major Pentatonic scale as it doesn’t contain any of the notes that traditionally clash with a Major chord.

In music, certain notes rub together and can create differing degrees of dissonance (clashes). These clashes are normally caused by a note in the melody being a semitone away from a note in the chord.

For example, the notes in the chord of A Major are A C# and E and the notes in the scale of A Major are A, B, C#, D, E, F#, and G#.

When we hear a chord being played, our ear locks onto the notes in the chord and hear them as the foundation of the melody being played. If the melody note is a note in the chord, then our ear accepts it as safe and at rest (or consonant). If the melody note is a tone away from a chord tone (for example B is a tone away from both A and C#, and F# is a tone away from E in the above example), then our ears perceive a pleasing richness to the chord.

However, if the melody note is only a semitone away from a chord tone, then our ears hear a clash that we feel needs to resolve. For example, the 4th of the A Major scale (D) is only a semitone away from the 3rd (C#) and thus needs to resolve. The 7th of the A Major scale (G#) is only a semitone below the root (A) and also normally wants to resolve up to the A root.

The Major Pentatonic scale is commonly used in pop because it does not contain a 4th or a 7th so every note sounds rich and pleasing against the harmony.

While Major Pentatonic scales are rarely used over Minor chords, it is very common for Minor Pentatonic scales to be used over Major chords as we will see in the following chapter.
