Sound Art is an artistic discipline where sound is used as the primary medium. Like other contemporary art genres, Sound Art is inherently interdisciplinary, engaging with a variety of subjects including electronics, acoustics, noise music, psychoacoustics, audio media, video, film, and sculpture. Early examples of Sound Art include Luigi Russolo's noise intoners, as well as experimental works by Surrealists, Dadaists, and the Fluxus movement. These early pioneers helped establish sound as a legitimate medium for artistic expression.

Etching is a technique where a design is created on a metal surface by using a strong acid or mordant to eat away the unprotected parts of the metal, leaving the desired pattern in relief (intaglio). In modern art and manufacturing, different chemicals may be used depending on the material being etched.
