Watch the Bobby Green online guitar lesson by David Hamburger from Fingerstyle Blues Factory
Robert Johnson meets Freddie Green! Green being the rhythm guitarist in the Count Basie band for nearly fifty years and the heavyweight champ of the self-effacing, big band-propelling rhythm guitar style known as four on the floor or, more usually, just "Freddie Green style." Measure 1 is the all-time classic Delta blues walkdown in A, as exemplified by Johnson but played by nearly everyone. Observe how we’re holding the root constant on top against the descending line on the fourth string – that descending line is implying the descending diminished chords we've seen elswhere. Measure 2 incorporates a quintessential Green voicing, a seventh chord with the fifth in the bass.
