Watch the Pentatonic Scale online guitar lesson by Brad Carlton from Melodic Patterns
Pentatonic Scale Example 2 turns this scale around because you're ascending, going from the low A all the way up to the high C. But each motif, or idea that occurs on each string, is a descending high-low pattern. On the sixth string you go from C to A, then on the fifth string from E to D and so on. So as you ascend through the pattern each two-note group is a descending motif. This helps you break out of the rut of just walking up and down scales.
