A few vibrato queries.
Because searching for vibrato is like trying to find a needle in a haystack full of needles in this place, permit me to ask a few questions I have, since I've found no definitive vibrato master thread anywhere. And if there is one, hit me over the head and point me there.
Point of interest A: vibrato on the high E. How are you supposed to approach it? I've seen vibrato explained as a series of miniature bends, but that just doesn't want to work for me on the high E. My vibrato up to now is a sort of take on Clapton's style (i.e. you take your hand off the back of the neck) because I just can't seem to get the hang of vibrato with the hand ON the back of the neck - which is all fine and dandy, except I end up wiggling the string aimlessly. I've been cheating my way a little bit with the tremolo arm, but tremolo vibrato is... well, it's tremolo vibrato. It's not as "natural" as the real thing, even when pulling only up (that is to say going above the pitch and back to it).
Point of interest B: metal vibrato - that really wide, aggressive vibrato - think... Slayer or something. Sure, my vibrato's improved somewhat lately, but I just can't seem to get a good enough grip. Don't get me wrong, I do practice with every occasion (that is once every few days, recently, but generally once a day) but I seem to miss the right way of doing it.
