Circles is a composition for female voice, harp and two percussionists by the Italian composer Luciano Berio.
The work followed by two years the landmark composition Thema (Omaggio a Joyce) in which Berio deconstructed Berberian's voice through the use of innovative electronic manipulation.
[2] Throughout Circles Berio explores similar sound textures while limiting himself exclusively to acoustic means.
Berio follows an ABCBA arch form in Circles (the text from the first two poems being repeated with a different setting).
She is also required to perform on specific percussion instruments such as finger cymbals, claves, and various kinds of chimes.
