Watch the E add 9, D add 9/E Vamp online guitar lesson by Brad Carlton from Guitar Lab: The Golden Arp

This lesson uses an E add 9 and a D add 9 over an E bass note (pedal tone) as it's jam track. We'll start by playing all four inversions of the drop 2 add 9 chords on the top four strings for each chord. Then we'll apply voice leading and scale application to connect the chords in a smooth musical fashion.
