Examples 1 and 2 show the two positions as they are normally played and Example 3 is the three note per string combination of the two positions.
Example 4 is a descending four note sequence using both positions. Use alternate picking on this one. It's much easier to perform a pattern like this using a three note per string scale on guitar than the standard two note per string scale. The fourths can make the fingers trip over themselves sometimes, stretching out to a higher position alleviates some of the awkwardness. Example 5 is the same pattern in ascending form.
Example 6 is a legato three note per string scale with some string skipping. Real easy to fly through this one, but not so easy to keep everything rhythmically smooth. USE A METRONOME!
Example 7 combines all three positions of Pentatonic covered so far by using left hand tapping for the upper position. Again. timing is key. Start with the metronome slow and gradually work up the tempo.
