Ferreyra was born in Cordoba, Argentina, and studied piano with Celia Bronstein in Buenos Aires.
She continued her study of music with Nadia Boulanger in Paris,[1] and worked with Earle Brown and György Ligeti in Germany.
The music by Ferreyra is important to weave together a sense of continuity as the film itself presents the contradictions of reality in these different scenarios.
[6] She worked with Bernard Baschet and his Structures Sonores in 1970, and served residencies in electronic music with Dartmouth College in 1976 and in 1998.
[9] Ferreyra continues to perform internationally commissioned works for concerts and festivals and has also previously composed for ballet, film, radio, television and music therapy.
