How to deepen the voice
 

How do you deepen your voice, to get a little more of a rock-voice? All I can do is very clean singing and it's kind of getting boring.

But do you mean like...rougher vocals? Or actually a lower pitch? I think there's ways to train your voice to be more pronounced at lower frequencies, but I'm not too sure if you can actually significantly "deepen" it.

Puberty works for most people. Other than than, no idea.

I meant rougher, not as in grunting or screaming.
