The Barroco na Bahia chamber choir is a philantropic organization with the purpose of promoting baroque and classical sacred music repertoires. Today, the choir has 55 members.  The choir sings compositions in the original language with a stress on authenticity. The repertoire includes music of Tomas Luis de Victoria, Orlando de Lasso, Claudio Monteverdi, Johann Sebastian Bach, Georg Friedrich Händel, Manoel Dias de Oliveira, Wolfgang Amadeus Mozart, Franz Schubert, Felix Mendelssohn Bartoldy, Gioacchino Rossini, Camille Saint Saens, Charles Gounod, Cesar Franck, Anton Bruckner, and others. The choir practice is held at the Baroque Cultural Center, on Mondays and Wednesdays, at 7:00 p.m.

The Chamber Choir participates in some of the Sunday concerts at the cathedral, in productions of the operas at the Castro Alves Theater, and the recording of compact discs. Normally to become a member of the chamber choir, the canditade has to study in the preparation choir and take a test.
