Watch the Rhythm Mojo Groove 2 online guitar lesson by Shane Theriot from Rhythm Mojo
Here's a fun little 1, 4, 5 groove in a Cajun/Zydeco feel. Notice the way I use the 9th chords. I then move on to straight bar chords (Driving Rhythm) but slide into the chords (Slipping and Slidin). I use the concept again with some higher 7th voicings just after this. I then move on to using the triads over the 1, 4, 5 progression, then move on to a descending 3rds idea. Then I use the rockabilly idea from the Zydeco groove in an earlier example.
