Nanã Das Águas is a Brazilian jazz and bossa nova tune performed by João Donato with lyrics by Geraldo Carneiro. It is generally listed as released in 1973, though the exact year is debated in some sources, and the track is not clearly tied to a single album in the material provided. The Portuguese lyrics weave a dreamlike scene around a figure named Nana, with imagery of diving behind rocks and the sea to reveal or conceal hidden truths, giving the song a moody, mystical atmosphere. João Donato, a celebrated Brazilian pianist and multi-instrumentalist, helped shape bossa nova and Brazilian jazz and was known for fusing Baião and Forró with Caribbean rhythms after living in the United States in the 1950s. This piece sits squarely in the Brazilian jazz and bossa nova tradition, showcasing Donato’s distinctive piano voice alongside Carneiro’s evocative lyrics.
