The Diminished Scale The diminished mode is way cool for playing over power chords. Tony Iommi of Black Sabbath used this quite a bit. It also works well with jazz. Remember, all you have to do to impliment this when you play, is to know which key you are playing in, and then put the root on the orange dot. It doesn't matter if its in the key of A, G, E, F or any other key, the root will always be in the same place. Notice how the root note shows up in a very regular pattern. Here's another pattern that can be used for playing the diminished mode: HOME BASIC CHORDS TUNING STRINGS GUITAR CARE LEARNING TABLATURE FINGER PATTERNS BACKING TRACKS SCALES AND MODES BLUES PATTERNS AMPLIFIERS RHAPSODY SUGGESTED BOOKS MY GUITARS
