@MetalManiac, Cue's right. The sheet is meant to be used with the Practical Music Theory Book. First you write down a chord equation: Dominate 7 = 1 3 5 b7. (You'll need to read the Practical Music Theory Book if you don't know what these are.) Then pick a key, say C, and then write down the notes in the chord according to the equation, C E G Bb. Then you find all occurances of those notes on the neck. Then you choose the notes grouped together to make chord grips.
