If you look at the positions of the root notes (key notes) in the scale pattern, you will notice that they form a triangular pattern. If you look at a basic E chord or an E form bar chord, you can see that the root notes are in the same positions as they are in the scale pattern. Because of this the scale pattern shown above can be described as the E form of the scale. It is also commonly called pattern 1.
Here is a lick (short phrase) derived from the E form of the minor pentatonic scale. It makes use of techniques such as the bend, the release, vibrato, the hammer-on and the pull-off.
