Watch the 8 Bar Blues'n online guitar lesson by David Blacker from Swing Blues Survival Guide: Rhythm

The 8 bar blues is a format used widely in swing blues, so it's good to get comfortable with the changes and possibilities. In this piece, we'll look at a double stop style approach to comping through an 8 bar blues in Bb. You can hear this kind of thing in the playing of guys like Hubert Sumlin, Hollywood Fats, Cliff Gallup, and others. Some classic 8 bar blues songs are numbers like "How Long Blues," "Sitting on Top of the World," and "Key to the Highway."
