This is the best $50.00 I've ever spent. The first part explains chord (forming chord). He then goes into progressions. He does a Thomas Whitified intro progression and then goes into 2-5-1 progressions and does different variations of these. He also explains chord substitutions and pedal points.
In the runs part pj talks about scales (major, melodic minor, harmonic minor, diminshed, whole-tone, blues, and pentatonic) and the various applications you can put them in. He also goes over some practice routines you can use to build up finger strength.
