Black & White, Sound, 3′20″ approx
“An algorithmically controlled audiovisual composition, using close-up footage of a strum on a single guitar string which has been fragmented into various fractional harmonic and discordant pitches and rhythms by speeding up different sections of the footage into the necessary fractions (1/1, 7/8, 5/6, 6/8, 4/6, 5/8, 1/2, 3/8, 1/3, 1/4, 1/6, 1/8).
In other words, 12 layers of 24 bars of repeated single string strumming are overlaid on top of each other (and separated on screen into their fractions) and each played at a different speed.” Andrew Quinn
