It's really difficult to explain how to sing over the internet. Even in person, it's difficult because you can't really "show" a person how your vocal chords work.

My advice would be to try and relax your neck/throat muscles as much as you can. And just sing for longer each time in small increments. The voice is a muscle, you should train it as such.

Also, don't be afraid to push the boundaries! I've increased my vocal range by a helluva lot just by experimenting. But if it starts to hurt then obviously you need to stop.

I used to have a voice like a Backstreet Boy. Hahahah.

Haha that's not a joke, that's probably where I do most of my singing (aside from band practices and recording)

Haha well... I've never recorded my voice using built-in mics.

Some people have a hard time (I know I did) getting used to what their voice sounds like recorded. It's because your voice sounds different when you're speaking... it's literally due to reverberation within your head. And you hear that in combination with what's coming out of your mouth.

Whereas when you record your voice, you don't have that reverberation in your head, so it sounds quite different to you. It can be quite jarring.

Or maybe you just need more practice

Record yourself as much as you can, I know that's helped my singing a lot.

Sorry, but that's the worst advice I've ever heard.

Listen to Chris Cornell during later-era Audioslave. His voice was completely f***ed due to bad technique, and he was mostly singing from his throat. And it sounded like shit.

He almost destroyed his magnificent voice. Then he got some proper advice and started singing better, and now he's better than ever.

Listen to Audioslave "Wide Awake" (the album version) vs Chris Cornell Songbook "Wide Awake" - look out for the high scream towards the end. You can hear the audible difference in his technique.

The danger is that a lot of rock singers generate the "grit" from their throat. I'm guilty of doing so myself. So it's a balance between good technique, and getting that rock n roll voice that everyone wants

The Zen of Screaming is a pretty useless video in terms of teaching you stuff, unfortunately. It's largely promotional and marketing material for that lady.
