For those of you metalheads out there, some of my favorite bands out there are King Diamond, Mercyful Fate, Death, Cynic, Pestilence, Atheist ect ect..now if there's one common thread with each of these, it's that they are progressive, technical, catchy and melodic. In my few years of striving to become a metal guitar god, I have learned different scales, basic chords, three string arpeggio sweeps..different patterns to comprise shred wankery at best. Now I learned a method, that at the begining of a practice session I will goof around on my guitar and create riffs and whatnot...but the progressions are weak and the patterns largely inconsistant. Any tips/techniques/chord progressions that will help me achieve a more structured, yet technical rythm base much like the afformentioned bands? Any advice would be greatly appreciated.
