We do scales, vocal exercises every day. I run the voice up and down, get as high as I can and as low as I can. I work on breathing, too.
Thousands of kids and parents come up to us and say, How do we get better as a singer?
About 10 years ago, I took some vocal lessons. I'll bet that helped. I got a tape of exercises that the girl gave me, which I don't do anymore, but they were good. And I don't smoke.
There is nothing more boring than doing singing exercises.
I have not practiced how to be a singer without an instrument.
I sing every day, on a regular basis.
When I do my vocal warm-ups everyone calls me the dolphin because I do stupid siren noises.
Each person's voice is very different, so you need to find what works for you. Make sure you keep to your routine.
