Monster/deep voice in death metal

How do singers get that kind of voice,I once knew how but stopped after I got out of the foster care thing.

Try using some basic screamo tips... that could help -

First off, there's more to it than just screaming. You have to know HOW to do it and what things to do... or else you'll f*ck up your vocal cords and sh*t. That wouldn't be too fun now would it?

Screamo sounds really awesome when done right. My advice to you is just practice. You won't sound EXACTLY like the bands who do screamo. Everybody who does screamo has their own unique sound. Just try to start out by testing different sounds and such... low, loud, in between. Each should have a different sound. DON'T PUSH YOURSELF. If your throat starts hurting or your voice starts slipping STOP. Don't risk hurting your vocal chords. Keep a drink like water, gatorade or whatever you drink, handy that way you can get a drink in between screaming. This is an important thing to do to keep your vocal chords moist, that way your vocals chords don't start getting dry. Be sure to take breaks from it too. Don't keep practicing 24/7. Get a drink before you start, in between *during your breaks from screaming* and after you've finished for the day/night. Don't try to be something your not either. If you don't get it, don't worry. Maybe you will some other time. Practice for a half hour or an hour and then stop for the time being and maybe try again later that night for another half hour or so. Be sure to take a few 10 minute breaks or so in between your practicing times too as I said before.

Just follow my advice and you should be fine. But like I said... if it hurts... STOP. Don't ever push yourself or else you'll cause damage to your throat/vocal cords and then you'll really be wishin you hadn't of pushed it huh?

Ignore the dumbas*es who just say stuff like uhhh... just scream or start by hating your life. Screamo has nothing to do with hating your life. And there's WAY more to it than just screaming.

I think that about covers things. If after all this, you still can't do it, or it causes pain. Give it up. Your voice/throat has probably changed forever and you wouldn't want to risk causing serious damage to your throat/vocal chords. Also, if you need anything else regarding this or something... don't be afraid to ask me because I'm very good when it comes to stuff like this haha

as mz10 said, you could use synth...
I prefer the original deep bass death vocals (six feet under, cannibal corpse, deicide)

the main trick is to do this to get the sound...

ok now youll need your throat to be moist, maybe drink a small amount of water or juice (I prefer juice)
now you know when you try to spit out Flem? try doing that but dont let it go to your mouth, we want to be able to roll it in the throat, if youre successful you should be getting some sort of growl...

now if you listen carefully youll notice youre actually growling an A... like aaahhh

now we dont want that... so what do we need to do? sing an O, you can do this by relaxing your throat while doing the flem juggling trick...
the more relaxed your throat, the lower the growl...

its not as hard as it sounds...
I've been doing black/death/doom vocals for over 5 years...
and thats my little secret...
if you do it correctly you should get a really scary death growl...
my bassist left the group because she couldnt hear her own playing when we were doing a cover of roots bloody roots (cannibal corpse style)

jmz10's answer rocks!!!lol
