Watch the Understanding Extensions online guitar lesson by TrueFire from The Indispensable Toolbox for Guitarists
Understanding Extensions - Demonstration is a video guitar lesson presented by Susan Mazer and is sourced from Hands On Guitar: Beyond Beginner.
In this lesson I'll teach you sus4, sus2, add9, and 6th chords. I choose the forms that are most often heard in contemporary music. These chord extensions add flavor to the sometimes boring triads. As you're practicing them, be sure to print out the chart that goes along with this lesson.
