Hello this might be the wrong place for this kind of post but I have been obsessed with Brakences' cover of complicated and it has motivated me to start singing!
That being said I was curious if anyone in this community could give me tips on how to practice to achieve this level of singing.
I want to be able to sing with his power and switch between high and low notes as fluidly as he does but I don't even know where to start practicing for that kind of thing.
(I understand if there aren't any tips here but I thought I'd ask anyway thank you!)
