Rhythmic Structure: There are two ‘timelines’, both beginning at time 0:00. One timeline begins at the top left corner of the canvas, traveling down the y-axis to the bottom left corner. This lasts for 119 seconds. The second timeline begins at the bottom right corner of the canvas, traveling leftwards along the x-axis toward the bottom left corner. This lasts for 114 seconds. Lengths are based on the dimensions of the painting, 119 x 114 cm. As the two timelines travel, whenever a line edge is encountered, an ‘event’ occurs. An event is a note, or series of notes, that lasts either 119 or 114 seconds depending on which axis it is traveling along. For example, the timeline traveling down the y-axis first encounters a horizontal red line at 0:02, triggering a note that lasts for 114 seconds. Thus the painting as a whole is slowly animated/woven over the span of 3 minutes and 56 seconds.
Melodic/Harmonic Structure: Each color has been assigned a base frequency and the y-axis is mapped to the harmonic series. So, the bottom edge of the painting can be thought of as the fundamental, the top edge an octave, with all lines on the the canvas quantized to the closest overtone in the series between the two. Thus, horizontal line tones are constant in pitch, whereas vertical lines will shift in pitch as they cross perpendicular lines of like color. Each axis has an additional significance. The x-axis represents stereo pan position, and the y-axis represents volume. So, horizontal line tones are constant in pitch and volume but their stereo position is dynamic. Vertical line tones are constant in stereo position, but dynamic in frequency and volume. Each color is assigned a waveshape, sine for yellow, saw for red and square for blue. The piece overall contains 15 sinewaves (one for each yellow line on the canvas), 4 saw waves (one for each red line) and 4 square waves (one for each blue line).
