There is a good probability that you can play a bunch of chords and go through most songs with relative ease. Perhaps you’re armed with your pentatonics in all five positions and a couple of other scales. But then again, you might be looking for something to take your playing to a higher level.
If you’re that sort of intermediate guitar player, then Dan Denley’s “Ripfire” guitar course. “Ripfire” is a 20-DVD collection of courses designed to take your guitar playing to the advanced realm. Some of the featured courses in Ripfire include How to Match Scales and Chords, Guitar Mysteries Solved, and Chord Swap Secrets.
