Maria Rosa Canelas (July 30, 1941 – June 10, 2004), better known as Rosinha de Valença, was a Brazilian composer, arranger and musician.

She is considered one of the best acoustic guitarists in Brazilian music and played with many famous artists, including Baden Powell, Sérgio Mendes, Sylvia Telles and Sivuca.

One year later, she performed in the big show O Fino da Bossa, at the Teatro Paramount in São Paulo.

In 1974, after another tour abroad, Valença organized her own band, which was composed of famous artists, such as João Donato, Copinha, Ivone Lara and Miúcha.

[citation needed] In 2000, Valença was honored by a benefit concert, organized by Jalusa Barcellos, member of Secretaria Estadual de Cultura, and presented by Sérgio Cabral.

The album was contributed to by many friends and professional fellows of Valença: Martinho da Vila, Ivone Lara, Alcione, Miúcha, Caetano Veloso, Chico Buarque, Joanna, Bebel Gilberto, Hermeto Pascoal, Turíbio Santos and Yamandu Costa.
