The minor pentatonic scale is a mode of the major
pentatonic scale.
This means that both scales use the same
notes but have different tonic notes ('tone centres').
When C is selected as tonic
note from the notes C, D, E, G and
A, the C major tonic chord (C E G) generates a major sounding scale.
When A is selected as tonic
note from the same notes (C, D, E, G and
A), the A minor tonic chord (A C E) generates a minor sounding scale.
Likewise the Eb major pentatonic scale uses the same notes
as the C minor pentatonic scale, but each scale has its
own unique tonic note.
The major and related minor tonic notes
are always an interval of a minor 3rd (3 semitones)
apart.
