Incised Lines

Incised Lines is a “visual score” for Percy Grainger’s “Electric Eye Tone Tool.” I produced graphite rubbings directly from chisel-cut sandstone in The Rocks district of Sydney. 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. 
I have produced two scores for the “Electric Eye Tone Tool”, as the instrument has been recreated and programmed by the composer Warren Burt. Incised Lines: Dawes Point will debut in a concert at the Illawarra Institute of Technology, 4 June 2007 at 7:00 PM. Dawes Point is evoked in the programming, with gradually shifting tones that call to mind the tide and wind.

Convict stonemasons shaped sandstone into architectural elements that are varied in surface effects, and which continue to serve as direct transcriptions of hard physical labor and artistry. The basic tools for shaping stone have remained nearly unchanged for centuries: mallet, chisels, and straight edge. With these tools stonemasons interpreted the plans (or scores) of Penal Colony period architects, such as the transported forger Francis Greenway. Many fine examples of the masons’ handiwork exist in The Rocks district, and I selected colonial period sites at Dawes Point and the Argyle Cut to poduce rubbings.

Only a handful of Francis Greenway’s structures survive to this day, and for Incised Lines: Dawes Point, I produced a rubbing from a Greenway designed gun battery that was rediscovered near one of the footings of the Sydney Harbour Bridge. The Argyle Cut is a deep rock passage, providing a direct connection between Millers Point and The Rocks. The daunting rock ridge was first cut in 1843 with convict workers employing hand tools. After their effort ground to a halt, the excavation was finally completed in 1867/1868 with explosives.
I first imagined producing this sort of score when visiting Port Arthur, Tasmania, where I observed that convict produced buildings were covered in a complex relief of chisel marks that resembled percussion music.
