Many theoretical accounts of sound art tend to treat it as a subcategory of either music or visual art. I argue that this dualism prevents many works of sound art from being fully appreciated. My subsequent attempt of finding a basis for a more comprehensive aesthetic of acoustic art forms is helped along by Trevor Wishart’s concept of ‘sonic art’. I follow Wishart’s insight that the status of music was changed by the invention of sound recording and go on to argue that an even more important ontological consequence of recording was the new possibility of storing and manipulating any acoustic event. This media-historic condition, which I refer to as ‘recordability’, spawned three distinct art forms with different degrees of abstraction – electroacoustic music in the tradition of Pierre Schaeffer, gallery-oriented sound art and radiogenic Ars Acustica. Introducing Ars Acustica, or radio art, as a third term provides some perspective on the music/sound art binarism. A brief look at the history of radio art aims at substantiating my claim that all art forms based on recordable sounds can be fruitfully discussed by appreciating their shared technological basis and the multiplicity of their reference systems rather than by subsuming one into another.
