Spatial music is composed music that intentionally exploits sound localization. Though present in Western music from biblical times in the form of the antiphon, as a component specific to new musical techniques the concept of spatial music (Raummusik, usually translated as "space music") was introduced as early as 1928 in Germany. The term spatialisation is connected especially with electroacoustic music to denote the projection and localization of sound sources in physical or virtual space or sound's spatial movement in space.
