This lesson continues on from the previous lesson, which featured a bluegrass lick played in all the bluegrass keys (B, E, A, D, G, C, F, and Bb). In this lesson Chad expands on the lick using the pentatonic scale, and shows you the lick over a I–IV–V–I progression in all those keys. This will help you build your bluegrass vocabulary in all the keys you’re likely to play in and make it easier for you to improvise on bluegrass songs. Chad walks you through the bluesy pentatonic lick in all the keys, giving you advice on fingering and positions.
