Watch the Behind Barres: Straight online guitar lesson by Corey Congilio from 50 Blues Rhythms You MUST Know
Example 6 is taking the concept of the power chords we used in the previous examples and moving it up the neck.
Notice that it's the same sound but, in a different part of the fretboard. I call these examples Behind Bars because your hands are in a barre chord shape or position but, you're not playing a full barre chord. These examples are going to lay the groundwork for more interesting progressions later.
To be blunt, these chords are probably my least favorite because they're a bit painful! You'll see what I mean and, we'll tackle the pain topic next.
