I’ve uploaded video documentation of Incised Lines, my visual score for Percy Grainger’s Electric Eye Tone Tool. 

Incised Lines is a work of sound art, produced as a visual score for an optical synthesizer created by composer Percy Grainger and Burnett Cross between 1954 - 61, and recreated by composer Dr. Warren Burt

I produced graphite rubbings directly from the chisel-cut sandstone foundation of a colonial period fort designed by Francis Greenway at Dawes Point, Sydney Harbour. 

The “electric eyes” of the instrument read the differences between marked and unmarked areas in the rubbings, sensing the mallet and chisel blows of long dead masons, sounding their labor. Variations in the graphite rubbings of the score are translated to shifts in pitches, stereo placement and volume.
