Pauline Oliveros, Distinguished Research Professor of Music at Rensselaer Polytechnic Institute and Darius Milhaud Composer in Residence at Mills College, is a composer, performer and humanitarian, and musical pioneer. Acclaimed internationally, for four decades she has explored sound, forging new ground for herself and others. Through Deep Listening Pieces and earlier Sonic Meditations, Oliveros introduced the concept of incorporating all environmental sounds into musical performance. To make a pleasurable experience of this requires focused concentration, skilled musicianship and strong improvisational skills, which are the hallmarks of Oliveros’ work. Oliveros uses an accordion which has been re-tuned in two different systems of her just intonation, in addition to electronics, to alter the sound of the accordion and to explore the individual characteristics of each room.
