I've been trying, trying and trying to learn screaming. I've been looking at fry, growling, yelling, what you will. But I just can't do it properly. I've given up on growling entirely, even though I'm in Bass/Baritone range and it should be extra easy for me. People say, use your diaphragm and then it comes automatically. Well it doesn't. I can't get it to rumble in my chest.
So I decided on screaming instead, and tried fry that people recommend because it isn't as harmful to your throat. Here is how I sound after a few weeks of trying to "get" it, it's fucking ridicolous. How do I improve from here?
