Watch the Second Line Groove online guitar lesson by Shane Theriot from Rhythm Mojo
The meat of this riff is the 3/2 clave idea - once you get that down, try adding the bass note ideas from the first concept. I added a few ideas with 3rds and also played around with the voicings (#9, 7ths, etc.) to keep things interesting. The triads also come into play here. I utilized a few triad shapes over the main groove. Once you get the feel of this down, you'll be able to easily come up with your own variations on this classic New Orleans groove.
