Sums & Differences

1978, 8:24 min, b&w, sound

In his early works, Hill explores the structural and organic relation of linguistics to electronic phenomena. He states, "Certain structural properties of video are revealed in an almost primal sense." In Sums & Differences, images of musical instruments and their corresponding sounds are sequentially switched at an increasingly rapid rate. Sound and image are modulated by the switching of multiples of vertical/horizontal sync pulses, creating a simultaneity of visual and aural information.
