Severino Dias de Oliveira (1930 – 2006), popularly known as Sivuca, was a Brazilian accordionist and guitarist. He is best known internationally
for his work with Scandinavian jazz musicians in the 1980s. His most famous songs are the Brazilian popular classic João e Maria with lyrics by
Chico Buarque and the accordion standard "Feira de Mangaio" (named after the artisan markets of North East Brazil). He is famous for his use of
makeshift instruments playing alongside conventional ones and for his versatility, fusing traditional regional styles such as forró and Chorinho
with jazz, bossa, classical, and other musical forms. Sivuca and Hermeto Pascoal, both versatile multi-instrumentalists with albinism, have
worked together and are sometimes confused with each other.
