This book and CD teaches excellent techniques to use for walking bass lines on guitar when playing in a duet format, either with another guitar player or with a singer or other instrumentalists. The idea of this book is to give a few answers to the question, How do I harmonize walking bass lines when I've never done it before?. We will take the principal chords, major 7, 6, dominant 7, minor, diminished, and minor 7 flat 5 and walk bass lines on the sixth or fifth string. Written in notation and tablature.
