Watch the Fingerpicking with Moving Bass online guitar lesson by Jennifer Batten from Rock Sauce for Rhythm Guitar
I’m fingerpicking a chord progression in the B section of "The Swarm" (from my CD "Momentum"). In the first part of it, the only thing that changes is the bass note. It's a common technique to use a bass pedal and move the chords above it. This is the reverse, where the chord stays the same and the bass is the main movement.
