Need help playing the electric guitar? (Iron Maiden, Wasted Years)?

Learn a variety of scale with the use of your index, middle, ring, and pinky. That is how I started and from then on learning fast runs was a breeze because you have established intellectual memory on your fingers keeping up with your right rhythmic hand. Practice, practice, I know it sounds boring and cliche but its true, the quicker you can teach yourself to control and pace your fingers the easier it is to overcome odd meter rhythms. Not a bad song from Maiden but I have always loved Aces High even though I outgrew the 80s stuff and am into more modern metal.
