How to sing like Steven Tyler?

Answer 1

The stereotypical Steven-Tyler-Screamm is making vocal vibrations (or just making sound with your vocal chords) by INhaling instead of exhaling. You know how air comes out of your mouth when you speak? Taker it in. At first, it'll sound creepy and hollow, but after a week of practice it should sound right. Don't hurt yourself trying b/c for some people, it's just not possible. ;-|

Answer 2

Nail your feet to the floor
