"Manhã de Carnaval" ("Manha De Carnaval"; also known as "Carnival Morning" and often called "Black Orpheus") is a Portuguese-language bossa nova song with music by Luiz Bonfá and lyrics by Antônio Maria. Bonfá composed it for the 1959 film Orfeu Negro, directed by Marcel Camus, where it serves as the principal theme. The film's soundtrack also included songs by Antônio Carlos Jobim and Vinícius de Moraes. Camus first rejected the song, but Bonfá convinced him that it was superior to the replacement he had written. The singing of the character Orfeu was dubbed by Agostinho dos Santos, whose recording appeared on the 1959 soundtrack LP on Fontana. The film won an Academy Award in 1960.
Among the first bossa nova pieces to gain popularity outside Brazil, the song is known in France as "La Chanson d'Orphée", and its melody is also called "Carnival" or "Theme from Black Orpheus". Carl Sigman wrote an English lyric, "A Day in the Life of a Fool", which became a jazz standard. Notable recordings include versions by João Gilberto (1959), Sylvia Telles (1961), Wayne Shorter (1961), Vince Guaraldi (1962), Miriam Makeba and Stan Getz.
