Pull-offs on the pentatonic scale
Simple as lifting your finger off the fretboard!
A pull-off is a way you play two certain notes on the guitar. Imagine it as a kind of opposite to the hammer-on. You are fretting two notes on the same string and then strike the string. After the sound is made you pull the string with the finger that frets the higher note and lift it off the fretboard. The lower note on the same string and fretted by a different finger will sound afterwards!
You will play two notes per string exclusively and you will always pick the first note with a downstroke and then perform a pull-off to sound the second note. Remember to always position your fingers in the 1-2-3-4 position (one fret one finger) so your fretting hand isn't flying all over the guitar but stays as still as possible.
Low run, high run and the full run on the 4th pattern
Here's the fourth pattern of the two note per string A minor pentatonic scale. Take a good look at it in case you're unfamiliar with it. You'll be playing three licks on this pattern. You can play them indefinitely and go as fast as you want, because it sounds really cool, but please only speed up the tempo when you're 100% comfortable with the current playing speed. The last thing you want is to practice a mistake, because if there's one thing more difficult than learning something, it's to unlearn it.
The first thing you'll play is the low run. Check it out:
Just play and repeat the pattern for as long as you can on your current speed. When it's the easisest thing in the world, speed it up for about 8 bpm. Also, mind the fingering. Use your index finger for the 7th fret, your ring finger for the 8th fret, ring finger for the 9th fret and the pinky for the 10th fret. And repeat until you're ready to hit the next one - the high run.
Again do the same as in the low pattern and practice it. When you're comfortable enough with it, check out and play the longer one:
This is a cool run, end it appropriately with an octave of the final note of the run - as written in the tabs.
