Watch the New Orleans Gumbo online guitar lesson by TrueFire from Play Blues Guitar 4: Rhythm Principles
New Orleans Gumbo - Song 5 is a video guitar lesson presented by Matthieu Brandt and is sourced from Chord Tricks For Electric Blues.
This example shows you how to tackle a New Orleans type groove with dominant 7th triads. These grooves can become rather thick and full with lots of instruments interacting with each other, however the bass and drums will often leave some space open and not fill up every beat. Playing improvised patterns with small triad shapes gives you the best chance to be heard, but not be in anybody's way.
