Watch the Mixolydian online guitar lesson by Chris Buono from Modes That Matter
A great way to bolster your blues playing from every angle is to employ new sounds in addition to the go-to pentatonic scales. A great source for blues-approved fodder is the Mixolydian mode. Here over a standard Mixo vamp in G you can begin to play some Mixolydian licks and to start to wrap your fingers and ears around the idea. For those of you married to two-note-per-string fingering be sure to refer to the PDF chart of fingerings and check out the two-note-per-string sets right after the single-string scale as well as the modal pentatonic scales at the end. Both will give you that feel as well as fresh ideas to combine with your pentatonic licks.
