Once more to the diminished well. This turnaround is yet another way to juxtapose descending diminished voicings with a root pedal point. “Pedal point” being a slick classical music term that basically means “repeating a particular note while other things change around it.” Until the end of the second measure, we’re using just two notes at a time, on the 3rd and 2nd strings, as shorthand for the full diminished voicings. Then the upper bass notes, on the 4th string, start moving as part of the diminished voicings as well, so that we start measure 3 and end measure 4 using our by-now-familiar friend, the fifth-fret Robert Johnson voicing.
