this is where i think metal has the biggest contradiction. metal was never supposed to be harmonicly perfect, in fact metal has more in common with punk rock then the blues. punk rock got its start in britian from disenchanted metal heads who didnt like the way metal was turning into hair metal when metal became more main stream and producers got their hands into more and more and felt again like they were abandoned by soceity.

if the best metal has both a rough edge and vurtuosity(sp). the rough edge comes from the speed and over all design of the riffs (the open E played in termolo picking over either double base drums or a pounding tom) but speed and the knowledge the desgin powerful riffs only comes from the study of theory and dedicated practice. today most metal is not written and played in the studio but built using 10 to 15 different guitar tracks overlaid and then refined to the finished product. the truest end to metal wasnt kurt cobain it was priests hell bent for leather and kiss' make up and boots, iron maidens eddie, and bon jovis hair. ROCK IS SPECTCALE.

so here is my theory, perfect metal is never perfect. it must be flawed but also must be built around solid theory and experence. harmonicly speaking following modes and scales to the letter will never create metal that has the tone to become perfect (i give zakk wylde as an example, he is an awsome player but to me his music lacks a certain jump or hook) wheres as adding sharps or flats or even jumping intervals when a mode says otherwise.

this is just my 3 cents and my theory. it is by no means perfect and is still under a great deal of work.
