Can you tell me how I become a contry singer at 10 years old please?

To be a singer you need to sing, that's all there is to it. If you want earn money as a signer then you need to find jobs that pay you to sing. That's harder at 10.

You would be taking music lessons, learning to read music and know music theory. Then you take voice lessons and learn tone, breath control along with pitch.

And you practice, practice and practice. After that you will need your parents to be helping to find open mikes, karoke and other music events for you to perform at
