How do you death growl like Tim Lambesis of As I Lay Dying?

The following information I am giving you is from personal experience as a person who can growl well. It is not a lesson by any means but it will get you started. By the way, the good death metal singers out there do not use vocal changers, so whoever replied to this post originally is an idiot. By the way, growling is not harful to you nor does it bring about pain. If it does, you are definitely doing it wrong and your growl sounds like crap (because you are doing it wrong)

Tim does not growl, not even close. He uses a screaming technique that does not hurt his voice, that's all. Growling is much more (tuneful, characterized, whatever you want to call it) and it is MUCH harder to do than screaming. It resembles singing in many ways, and takes a lot of practice. Learn how to breathe properly from your diaphragm first. If you don't take the sweet time to do that first then forget trying to growl. After that try to sing a single note WITHOUT USING YOUR VOCAL CHORDS. It will be deep in your throat at first. But when you actually learn to growl, you will feel vibration in between your collar bone or very close to it. You must also keep your throat as open as possible without tightening up. Learn to manipulate the air (very important) to get the growl sound. There are also many other things to learn, but start out with that. By the way, listen to bands with true growling to hear what it actually sounds like such as Opeth, Nile, Dark Tranquility, Amon Amarth are very good examples.

A good way to do the sreamo teckneak is to eat hot cheetos or any thing spicy and drink hot tea so that the spit gets thik so it wont hurt as bad
