Watch the Western Swing Lead 2 online guitar lesson by Joe Dalton from 50 Country Guitar Licks You MUST Know

Adding a chromatic line to your bag of licks and tricks gives you a melodic choice to break things up a bit.

Then we have an arpeggio (single notes from the chord). Some of the coolness of the lick comes from combining these two features.
