Braga studied architecture in his youth, and, when he started to write songs, he adopted the pseudonym "João de Barro" (the name of a bird that builds elaborate mud nests), as his father wouldn't approve of seeing the family name associated with the world of samba and popular music, then on the fringes of society.

Braguinha is most famous for his Carnaval marchinhas (a genre of light-hearted songs related rhythmically to the military march).

His marchinhas have been recorded by some of the best-known Carnaval singers of the 20th century, such as Carmen Miranda.

In 1937, Braguinha wrote the lyrics to "Carinhoso", composed by Pixinguinha twenty years earlier.

Another beloved classic, the lyrical "Pastorinhas", was written in collaboration with legendary samba composer Noel Rosa.
