Watch the Guide Tone/Root Structures online guitar lesson by Brad Carlton from Guitar Lab: ii V I Options
This lesson is really quite simple. There are times when you do not want to include the root as your lowest voice, so in this lesson we are going to take everything you learned in lesson one and delete the root. Your bass player will love you for this skill and perhaps your pianist too.
This lesson will use diagrams 44 through 46 and examples 92 through 96.
