Watch the C# Funky Vamp online guitar lesson by Robben Ford from Riff Revolution
In the next eight, I play again the C# raised 9 chord, hitting the low C#. Then, we have this little move I picked up from playing with Miles Davis, which he taught to the keyboard player. It's in the key of C#, it's like playing a C triad with a C# in the root, then resolving so you have a C minor add4.
Second time through, I'm trying to expand rhythmically so I can open it up a little more. I'll hit little pops and accents that I won't play again to add interest.
