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.
"One of my favorite Mariah Carey tracks, if not THE favorite. The song message is of a lover who believes despite the current trials, she and her lover will be together once more. I am the one to end and never look back; you either agree with the messages of the song, or enjoy in hearing another's experience of love."
