over the past century, an art form has emerged between the realms of visual art and music. created by composers and sculptors, ‘sound art’ challenges fundamental divisions between these two sister arts and may be found in museums, festivals or public sites. works of sound art play on the fringes of our often-unconscious aural experience of a world dominated by the visual. this work addresses our ears in surprising ways: it is not strictly music, or noise, or speech, or any sound found in nature, but often includes, combines and transforms elements of all of these. sound art sculpts sound in space and time, reacts to environments and reshapes them, and frames ambient ‘found sound’, altering our concepts of space, time, music and noise.
