Filmusic Part 2 uses horizontal stripes, ranging from thick to thin, printed directly onto the film stock of photographic negatives. The stripes are read as both pictures and sound image, producing a ‘square wave’ tone whose pitch is determined by the frequency of the stripes. Two prints of this film are projected side by side, one of them back to front. – C.G. – See more at: https://lux.org.uk/collection/works/filmusic-part-2#sthash.0SU5dinF.dpuf
