It is easier to define Dionne Warwick by what she isn't rather than what she is. Although she grew up singing in church, she is not a gospel singer. Ella Fitzgerald and Sarah Vaughan are clear influences, but she is not a jazz singer. R&B is also part of her background, but she is not really a soul singer, either, at least not in the sense that Aretha Franklin is. Sophisticated is a word often used to describe her musical approach and the music she sings, but she is not a singer of standards such as Lena Horne or Nancy Wilson. What is she, then?
