'Sound Art' Wikipedia definition

Sound art is a diverse group of art practices that considers wide notions of sound, listening and hearing as its predominant focus. There are often distinct relationships forged between the visual and aural domains of art and perception by sound artists.
Like many genres of contemporary art, sound art is interdisciplinary in nature, or takes on hybrid forms. Sound art often engages with the subjects of acoustics, psychoacoustics, electronics, noise music, audio media and technology (both analog and digital), found or environmental sound, explorations of the human body, sculpture, film or video and an ever-expanding set of subjects that are part of the current discourse of contemporary art.
From the Western art historical tradition early examples include Luigi Russolo's Intonarumori or noise intoners, and subsequent experiments by Dadaists, Surrealists, the Situationist International, and in Fluxus happenings. Because of the diversity of sound art, there is often debate about whether sound art falls inside and/or outside of both the visual art and experimental music categories.
Other artistic lineages from which sound art emerges are conceptual art, minimalism, site-specific art, sound poetry, spoken word, avant garde poetry, and experimental theatre. Early practitioners include Tristan Tzara, Kurt Schwitters, Filippo Tommaso Marinetti, Hugo Ball and Henri-Martin Barzun.
