With each lesson that I've learned here in the core system and then going thru others such as the 12 barre course and even some of the metal courses... I will practice just my chords... like for instance.. with the course that Christopher Schlegel has on the 12 barre blues, he has a jazzy style of picking that set.. I will use that style and just strum my As then my Cs and so on.. not really following a song but just practicing those chords. You'd be surprised at how some of the practice sessions wind up coming out. And just picking on the acoustic practicing my finger picking pattern that Lisa McCormick has here... All the Pretty Horses is a good one that has the actual chord changes and helps train a few things at once... I use the actual songs there to learn what the pros do. Get away from the harder things :D I find that tons of the songs that have the power chords that have most of those folks famous a lot easier than the actual practicing the harmonics and getting the fundamentals down...May just be me though...
