I just did a vocal cover of Chris Cornell's song Gasoline. Check it out here:
When I first started singing, songs like this were absolutely impossible...even the notes in the verses would have been way out of my comfort zone.
I used to go to teachers, read forums and they'd all say the same thing: "bridge into headvoice! Don't worry if it sounds weak, it'll get stronger later!"
But it never did.
In this song I'm in chest voice the entire time, even the high B4 screams I do. It's all chest voice.
The distorted screams I do on those B4's all stem from pure chest voice. The way I developed those and teach it is by first being able to really lean in and powerfully hit those notes CLEAN and LOUD first in a lower larynx position (almost like an operatic kind of sound).
Yes it can be done safely. In fact, once it's strong you can sing for hours with a ton of stamina. One of my students who has been struggling through his gigs told me that once he started working with me his stamina has improved dramatically...EVEN THOUGH HE'S SINGING LOUDER in his gigs!!
I help singers get the vocal range, power, control and versatility to sing tough material like this with CONFIDENCE. If you're interested in working with me to get your voice to the next level reach out and contact me.
