Watch the Boogie: Bass & Chromatic online guitar lesson by Walter Broes from Rock, Billy, & Boogie Guidebook
Here we're really looking over the bass player’s shoulder for inspiration. Walking bass lines and chromatic connecting notes between chord and scale tones can make boogie patterns a lot less generic, and sound a little busier to add excitement to a tune.
This, again, can be a little more involved than it sounds, so take it slow and take your time to figure this type of thing out. You can hear great examples of this type of playing in 50’s R&B and jump blues, and of course paying attention to what the bass player is doing is a great idea!
