A minor and A minor Pentatonic
This diagram shows the connection between the A minor scale and the A minor Pentatonic scale. You know that the A minor Pentatonic scale is derived from the A minor scale by dropping the 2nd(B) and 6th(F) tones of the A minor scale leaving only the A, C, D, E and G notes. This diagram is somewhat different from the bazillion A minor pentatonic diagrams out there in that the notes of the A minor scale that are dropped are shown with thick red borders.
The utility of this is to demonstrate how easily you can transition from the A minor to the A minor Pentatonic and vice-versa. We can't tell you when you will want to do this - if you ever want to do this - but, if you do, you will know how.
You can significantly change the tonal flavor of a solo by dropping in and out of the full minor scale to the pentatonic version. Tastefully done, of course.
