Starting as a romantic singer, Rosana also had success in the disco and MPB styles with her gospel-tinged vocal interpretations. Singing since her early teens in her father's group, Casanova's, in 1981 she made her debut in the MPB Shell festival (TV Globo), but her first hit came only with "Nem Um Toque", from a demo tape that ended up being included in the nationwide TV Globo soap opera Roda de Fogo. The success was confirmed in 1987 with "O Amor e o Poder", for the also broadly popular soap opera of the same name. One of the most aired songs in that year, it also was included in her first LP, Coração Selvagem. Her 1989's LP Onde o Amor me Leva won the Sharp prize as the Best Record of the Year, while she also was awarded in the same year with the Globo Radio System trophy as the Best Singer of the Year, followed by performances in Portugal and Mexico. In 1990 he launched the Spanish version of that album for the Latin market, Por Donde el Amor me Lleva and the unedited Doce Pecado, which had a hit with "Riscos do Amor", included in the soundtrack of the soap opera Salomé (TV Globo). Awarded in the same year with the Imprensa trophy as the Best Singer of the Year, in 1994 Essa Sou Eu brought her the Sharp prize in the same category. Her disco-oriented Vende Peixe-se (1996) had a hit with "Linha de Fogo", included in the soundtrack of the TV Globo series Malhação. After a period retired to look after her newborn child, she returned to the artistic scene in 1999, participating in the commemorations of the Banco do Brasil Culture center for the 90 years of Carmen Miranda's birth.
