Not again... after so many years I come back to see the same old stuff?!?!
Anything to do with tonality, or dissonance, or atonality, or whatever you want to call it is simply: tools! Some work better for some workers, others work better for other workers! You can't make a house with only a hammer in your hand (unless you didn't have any other equipment in which case you would be forced at that) . You can't make anything beautiful with only a buldoser (?sp?) at hand... So you need everything and anything. Just learn about it and use it as you please (and of course I'm not talking to J. right? ;))
