Tips, Tricks and Tools To Help You Sing!

How do you Scream without taking vocal lessons, bands like atreyu, trivium, bfmv, aa that remains?

I want to learn how to scream, but i can't afford to take vocal lessons along with bass lessons.

practice inhaling and exhaling a lot, and just slowly work on doing simple growls before you try to scream words or lines. i'm starting to learn, as well. it's super hard =/
