The colours of the spectrum have a parallel in the octave of sound, and are related by systems of recognition developed in the human brain.
My Harmonic Chart logically representing the musical octave and its associated harmonics, was published as a screenprint in 1980. I began to make what I called scan cards by collaging parts cut from screenprinting seconds (which is part of the screenprint production process) of this Harmonic Chart.
The concept arose from seeing patterns established when electronically tracking the movements of the eye while a person is observing paintings. I realised these patterns of movements, allied with my system of the relationship of colour to sound, would produce sequences of sound that could be considered as musical improvisation.
This exhibition Notes and Crosses is derived from the naughts and crosses game and explores the myriad of possible musical sequences, arrived at by scanning the works in this exhibition.
