The fish belong to the river's contribution to Kĩsêdjê song. Like the mouse and the bee, the fish-people are held to possess songs that pass into human ceremony through those able to hear them, extending the Kĩsêdjê map of musical origins from forest and garden to the waters of the Xingu. Their inclusion underlines a consistent principle in Kĩsêdjê thought: the world's animal and spirit others are the true composers, and human ceremonial life is an ongoing gathering-in of their voices. Fish songs thus sit within a single cosmological economy of music that spans land, air and water.
