Joanna Bruzdowicz (born May 17, 1943 in Warsaw) is a Polish composer.
Bruzdowicz studied at the Warsaw Music High School, at the State Higher School of Music (composition with Kazimierz Sikorski and piano with Irena Protasiewicz and Wanda Osakiewicz); she earned her M.A. in 1966. She continued her studies in Paris on a scholarship from the French government and became a student of Nadia Boulanger, Olivier Messiaen and Pierre Schaeffer (1968–70). She joined the electroacoustic Groupe de Recherches Musicales and wrote her doctoral thesis "Mathematics and Logic in Contemporary Music" at the Sorbonne.
After completing her studies in France, she settled in Belgium with her husband, Horst-Jürgen Tittel, former top advisor to the president of the European Commission. Together, they created the 36-episode German TV series Stahlkammer Zürich for which Bruzdowicz wrote over 15 hours of music. They now live in the South of France. They have three sons: Mark, Jan and Jörg Tittel.
As a composer she devotes her attention to opera, symphonic and chamber music, works for children, and music for film and television. She wrote four concerti and numerous chamber pieces, as well as over 25 hours of film music. Her compositions are featured on 12 CDs and over 20 LPs; she has been featured in TV programs produced in Belgium, France, Germany and Poland.
Her output includes several operas which brought to the stage some of the greatest works of European literature (e.g. The Penal Colony, after Franz Kafka, 1972; The Women of Troy after Euripides, 1973; and The Gates of Paradise, after Jerzy Andrzejewski, 1987).
Bruzdowicz has a long-standing creative relationship with French film director Agnès Varda, for whom she composed soundtracks for movies from Sans Toit Ni Loi (engl. Vagabond, Golden Lion in Venice, 1985) to Les Glaneurs et la Glaneuse (engl. The Gleaners and I), her multiple award-winning documentary.
