1970s

From 1970, since her brother was no longer present, she began playing the chords as if there were two guitars. This is the audience perception at her performances. Some would say: "It’s like two guitars playing together!"

1980s

Grupo Lumiar emerged in 1982. At first, it was just a group of women playing a repertoire consisting mainly of Brazilian popular music, with emphasis on instrumental music. Flávia, Vânia Andrade, Isabel Queiroga, and Ana Áurea were the group’s members.  During the six years that the Lumiar stayed together, until 1988, the group has performed in several shows such as Espaço Aberto and Melhores do Ano and did a show in tribute to Elis Regina at the Casa da Arte in Recife.

During this period, Flávia was also carrying out her own projects, such as attending a course in harmony at the Seminar of Instrumental Music in Ouro Preto, Minas Gerais in 1986. She also studied at the Conservatório Pernambucano de Música and later, she got her degree in music at the Federal University of Pernambuco. She also took private lessons of flute and keyboard.

At her return to Recife, she started playing with Lula Gomes, and together they composed a frevo - "Folia do Povo," which got the 3rd place in a music festival called Frevança 88.
