Eunice Kathleen Waymon, better known by her stage name Nina Simone (February 21, 1933 – April 21, 2003), was an American singer, songwriter, pianist, arranger and civil rights activist.

Although she disliked being categorized, Simone is generally classified as a jazz musician. She preferred the term "Black Classical Music" herself. Simone originally aspired to become a classical pianist, but her work covers an eclectic variety of musical styles besides her classical basis, such as jazz, soul, folk, R&B, gospel, and pop music. Her vocal style (with a rich alto vocal range) is characterized by intense passion, breathiness, and tremolo.
