Mariah Carey, she's got great "lungs".
First i would add, nobody can just decide "Hey i wanna learn to sing" you have to own it's potential within yourself first then if you weren't able to open up to creativity of your voice and get over the tune, then you take help from teachers to help you cross your limits. So i don't really have this attitude to be a professional singer but if i wanted to do it, I'd try with nobody but the king Chester Charles Bennington.
My grade 9 music teacher. She had the most amazing voice, and is a very good vocal instructor.
When he was in his prime and still alive, I would want this man to teach me ! Jim Morrison.
Adele. She puts so much emotion into her voice. That is what I would like to come out in my voice. Unfortunately no one can help me sing. My vocal chords were damaged while be intubated during surgery. For three months I sounded like Minnie Mouse when I just talked. I am just happy to sound like a normal person when speaking again.
