How can I do high pitched screams like Dave Mustaine and Tom Araya in their early days? Does it have to do with the voice, something I can't change? Because Tom has a really hard voice, but he can do high pitched screams amazingly. I think I have a very hard voice too, perfect for death metal but that's not my style, I'm a thrash person

So, is it possible for me to do high pitched screams if I have a tough/hard voice? I don't know the right terminology, excuse me for that.
