Watch the Section 1: Jazz Patterns online guitar lesson by Brad Carlton from Rhythmology

Jazz uses extended harmony which can be broken down into triads and other smaller elements. In this lesson, we'll approach comping over major family chords in a swing feel. You will first learn triads and their inversions and then learn how to modify various voices to access different extensions.
