Did you know that there are six different pentatonic scales found within the major scale? Each one corresponds to each chord in the scale. For example, the notes of the C major scale are:
C D E F G A B
The chords to the C major scale are:
C Dm Em F G Am
All of the notes from the following pentatonic scales are found within the C major scale.
C major pentatonic scale C D E G A
D minor pentatonic scale D F G A C
E minor pentatonic scale E G A B D
F major pentatonic scale F G A C D
G major pentatonic scale G A B D E
A minor pentatonic scale A C D E G
As you can see, all of the notes from all the different pentatonic scales are notes found within the C major scale.
I left the seventh chord of the major scale out of this because it’s generally not used and it doesn’t have a correspond pentatonic like the others.
