Sofia Gubaidulina, composer, who "explored the tension between the human and the divine, and sought to place her music in the service of religion," died last Thursday, age 93. Her music was often noted for its spiritual, sometimes explicitly liturgical, qualities as well as for the inspiration she drew from sources as diverse as folk musics, Japanese music, the Fibonacci series, and alternate tuning systems.
"To Soviet critics, her microchromatic tunings were 'irresponsible' and Astreia’s improvisations a form of 'hooliganism.' The dark sound palette and mystical spaciousness of her music ran counter to the tuneful optimism favored by Soviet officials. In 1979, Tikhon Khrennikov, the head of the powerful Composer’s Union, added Ms. Gubaidulina to a blacklist."
