Watch the beginning of this arrangement of "You got to walk that lonesome valley" to see how the picking pattern is modified to match the left hand
The left hand is building up and breaking down parts of the G Chord.
This continues throughout the arrangement as the first position G Chord shape is slid up and down the neck.
The only fretted chords in this classic Son House bottleneck blues are barres with a 7th added on the high string.
