American composer and accordionist Pauline Oliveros has died at the age of 84.
The musician passed away on Friday (25Nov16).
Oliveros is best known for her sonic meditation and deep-listening music theories, described as the "difference between the involuntary nature of hearing and the voluntary, selective nature..."
In the 1980s, Oliveros formed the Deep Listening Band and the Pauline Oliveros Foundation.
The composer was also a founder of the San Francisco Tape Music Center and taught music at Mills College, the University of California, San Diego (UCSD), Oberlin Conservatory of Music, and Rensselaer Polytechnic Institute.
She received a number of accolades throughout her career, including the Resounding Vision Award from Nameless Sound and the John Cage Award from the Foundation for Contemporary Arts. Oliveros was also the author of several books, including Initiation Dream, Software for People, and Deep Listening: A Composer's Sound Practice.
