Watch the Permutations of Root online guitar lesson by Brad Carlton from Guitar Lab: The Golden Arp
For this lesson I'll take a two-two form in 2nd inversion and apply patterns from column three of the permutation chart. By alternating between patterns one and two in column three, I can build a great funk "bubble" part. I'll then demonstrate playing the part both monophonically and polyphonically. This will introduce harmonic finger rolls vs. melodic finger rolls. You will become aware of your options regarding the control of the number of voices ringing at any given time.
