Mariah Carey - Without You. Mariah Carey is also one of my favorite female vocalists. She is so expressive (one of the most important parts of singing well - most amateurs don't give enough expression to their singing!) - and she has a tremendous range. She is one of the few singers who use what's called a "whistle range"; a very, very high pitch that not many are capable of. It's a trick of the vocal cords. I'll post one of her songs where she uses this.
