Question:

Do u need to know notes to become professional singer?

Best Answer - Chosen by Asker: It helps a lot if you can read music. If you can the producer can just hand you sheet music , for you to read and sing.

If you cant read music , then he needs to get someone to play it and try to teach it that way.

Either way can work if you can quickly pick up the melody and words to the song.
