Watch the Rhythm Fill online guitar lesson by Joe Dalton from 50 Country Guitar Licks You MUST Know
In a more modern country setting, you may find the need to fill during a rhythm part. This fill uses the flatted third and the flatted seventh. The chords are strummed. I don't use hybrid picking in these types of rhythm parts. Dig in hard on the notes, but use a lighter, not too light, touch on the chords. You need to listen to some Brad Paisley.
