Maracatu de baque virado

Maracatu nação is the Afro-Brazilian procession music of Recife (Pernambuco), played by the nações for the coronation of their kings: a wall of alfaias (rope-tuned bass drums), a caixa snare roll, the gonguê bell and the abê shaker. The baque virado is its basic beat. The alfaias play the 3-3-2 sixteenth cell (dotted-eighth, dotted-eighth, eighth) with the heaviest strokes on the beat, the caixa fills every eighth, the gonguê keeps a bell line that resolves on the and-of-3, and the second bar "turns" (vira) with extra alfaia strokes into the downbeat. A bass doubles the alfaias here so the groove has a pitch. Chico Science's mangue beat and much Brazilian pop since the 1990s start from this.
