Play the notes of the scale up and down in each of these five positions, starting on the root of the scale. Play down to the lowest note in the position and back up again. Then, play up to the highest note and back down to the root. Keep the rhythm consistent as you go.
Once you get comfortable playing the scale in each position, try shifting between positions while playing it. Improvise solos in the scale, ranging all over the fretboard.
You can use a minor pentatonic scale anytime you are playing in a minor key or over a minor chord. It's a great way to make bass lines that are simple and sound good, or to take a bass solo. Knowing this scale will make the blues, major pentatonic and minor scales easy to learn.
