Apparently sucking your gut (diaphram) in helps with hitting both low and high notes. Also: Do not tense up in the head when you sing your high notes, you need to relax your muscles to best hit them.
Personally I like to sing in what I call waver-tone (It sort of gives your vocal delivery an anxious feel)
Personally again, I like to give my singing a sort of "gritty-ness" Kinda like Bob Dylan meets underground metal. That might sound funny but, if I got my idea across, hey no complaints.
