Often called the pope of Brazilian Modernism, Mário de Andrade spearheaded several different phases of the movement, and is credited with introducing the term modernismo in Brazil. From pioneering the experimental first wave of Brazilian Modernism of 1922–26 to sombre reflections on national identity in the mid-1930s–1940s and moving among poetry, short fiction, essays, musicology, travel writing, and the novel Macunaíma (1928), his output is extraordinary in both its volume and its influence. Despite his shifting registers and genres, the major preoccupations of his works remain constant throughout his lengthy career: Brazilian national identity and fraught encounters between different cultures, ethnicities, and worldviews; linguistic experimentation, especially the relationship between writing and orality; and music.
