ummm i think you should just go in a quiet place and scream your hearts out!! to make it sound like a screamo screamo scream though, try making it lower. its fun!!!

get fu-cked in the as-s

Drop an anvil on your foot. Trust me, you'll scream.

Place your penis on a brick and slam another brick on top of the first brick. What a pity you have no talent that you have to resort to screaming.

First off, this is the "singing" forum, so you're not going to find a lot of support here. That said, you need to figure out what kind of screaming you want to do...high, nasally screamo or a more deathy, growly screamo. Once you know that, record your voice on tape...play it back to hear what it sounds like...make adjustments...and practice, practice, practice. Eventually your voice will be beat into submission and the scream will come naturally. Just like any workout though, its gonna hurt for awhile, so be prepared. Oh, and forget about going back into normal singing anytime in the future as well, if you do. The vocal chords aren't designed for that kind of punishment and there's really no "healthy" way to be a screamo guy.

I recommend the Zen of Screaming DVD by Melissa Cross. She's helped train a bunch of singers/screamers in bands similar to those. And it's actually very helpful.
