Águas da Amazônia, Sete ou oito peças para um balé (Portuguese for 'Waters of the Amazon, seven or eight pieces for a ballet'), is a 1993–99 musical composition by the American contemporary classical composer Philip Glass.
Originally composed as a dance score for a ballet company of Belo Horizonte (Grupo Corpo),[1] following the introduction between Uakti and Philip Glass by Paul Simon, it draws inspiration from the Amazon waters with tones of classical, new age, and jazz music.
The track listing dedicates each song to one of the rivers: A last title much in the same style but departing from this nomenclature is also part of the album: Glass composed the music which the group performed under the artistic direction of, and with arrangements by, Marco Antônio Guimarães [pt] (also at the strings).
Paulo Sérgio dos Santos and Décio de Souza Ramos Filho played the percussion instruments and Artur Andrés Ribeiro the woodwinds.
In 2017, Charles Coleman released an orchestral arrangement of the work featuring the MDR Leipzig Radio Symphony Orchestra and Absolute Ensemble, conducted by Kristjan Jarvi.
