I need help death screaming?

[KellyT]

Don't girls have to do it different to boys? Because I tried it as a boy's method and it didn't work. Detailed answers please. I want to be able to do it like the lead singer of Flyleaf.

Listen to an album that showcases harsh vocal techniques. Good bands include Deicide, Morbid Angel, Cannibal Corpse, Dying Fetus, Behemoth, Hate Eternal, Vader, or Death.
Warm up your voice before recording or performing death metal. "Warming up" can mean anything from singing mid-tone melodies to delivering your vocal patterns in a clean chest tone. Even humming for five minutes would be more beneficial to you than not warming up your voice at all.
When performing live, drink lukewarm water or tea an hour before performing, as well as in between songs. Avoid cold water, as it shocks the voice. Following these simple guidelines will help protect and strengthen your vocal chords. If you don't sing properly, you may not be singing for much longer.
Learn how to sing properly. Start with something with vibrato, like Classic Rock or Progressive, i.e. Nevermore. The most important technique for performing death metal vocals is to be able to control your breathing, establishing a balance between the force used by your diaphragm and vocal cords. Using only the vocal cords will put undue pressure on them and is sure to damage them (minor damage will heal in time). Proper technique is established by using the diaphragm to push air out of your lungs.
Fill up your lungs with air, then push out some of the air, tightening your throat and moving your tonsils as you do this. Do this all in one motion, but don't push too hard. Aim the sound higher in your throat to make a "dying old man"-like sound. It should sound something like a black metal raspy voice. From there lower the pitch in your throat the same way you would with your normal voice. At first, it won’t sound like much-- it takes some time to get used to.
Pick a lyric you want to perform. Try to choose songs from bands like Slayer, Metallica, AC/DC or other bands who do not use the death grunts, as it will be easier to rehearse your grunts (Six Feet Under has redone classic rock songs and given them a Death Metal makeover). Try singing it normally, then slowly add more "fire" to it, until you can feel your diaphragm really pushing and you're getting that deep sound you're looking for. If you don't succeed in the deep guttural vocals try the raspier approach to these vocals like Mark Hunter of Chimaira. Anyone can achieve this, men as well as women (listen to the current vocalist for Arch Enemy), as long as their vocal range is Alto or lower. Arch Enemy's Vocalist Angela Gossow is an alto, and will say it herself--if you are a Soprano, don't even try Death Growls.
Practice barking like a dog. Take a deep breath and go from your diaphragm. Force the sound out from the bottom of your belly, really imitating the barking sound. Then extend the barking sound and try it with several words. Breathing like a dog, as stupid as it sounds, can help you open your throat and get a guttural sound to your grunts. Don't do it loudly at the beginning--increase your volume as you get better at it.
After you've mastered basic death grunts, move on to bigger things. Make your grunts louder, faster, lower, deeper, or all of the above. It will help add some variety to your vocals.
After you've mastered death metal vocals, try to mix things up by learning another vocal style--even the best death metal vocalists don't use only death grunts in their songs. For example, George Fisher of Cannibal Corpse is known for having high-pitched screams in a few of his songs and Trevor Strand of The Black Dahlia Murder has been known for using a mix of death grunts, high-pitched shrieking and screaming. Also, start headbanging when you're performing the vocals. It will make your presentation seem a lot more intense!
After you're done performing death metal vocals, be sure to drink a healthful beverage such as the universal choice, water. Milk is also a good choice as it provides proteins and naturally produces phlegm, which will help to soothe and coat your throat. (Note that if your throat is sore, you're most likely doing something wrong.) Don't drink juice-- it contains citric acid, which will eat away at your throat.
