Not sure if this is the right place, but oh well. I need help with screaming in songs. I can't really keep my voice high enough for very long. Any tips would be appreciated.

Oh, and try to keep the explainations as simple as possible, I don't understand alot of the music notes.
Of course, you'll want to make sure you've got enough air to sustain however long.
Also, it really depends how you want to scream.

I kinda want to scream like M. Shadows of Avenged Sevenfold. Like in Unholy Confessions, Beast And The Harlot, and Eternal Rest.
