Sound is conventionally used in commercial cinema to underline the emotional impact of the narrative, playing a supporting role to the image.

In artists' film, filmmakers have freed up sound from this traditional use and have questioned how sound works: how sound can be an end in itself.

The idea of synchronised sound was only made technically possible after three decades of silent filmmaking. A visual language had already evolved which didn't require sound interpretation for audiences to understand narrative. Artists have continued to evolve this visual narrative [it's worth considering the value of silence as an alternative to sound] as well as explore the possibilities of sound as an autonomous element.

From unsynchronised incongruity to harmony, sound is a medium of experimentation.
