440.0 Hz

440.0 Hz. was shot with a spy camera that was placed inside the mouth. Beck and Calvo then walked down the busy streets in New York City and recorded what they encountered. The change in audio from breath to pitch as the mouth opens and closes creates a bridge from the interiority of thought and body function to the exteriority of the individual as part of public life. 440.0 Hz is a standard reference pitch, for example a tone that is used by symphonies for tuning- the ultimate referent.
