An eclipse is a flirtatious dance between the sun, moon, and earth. Graphing the movements of solar and lunar eclipses, sunrise/sunset, and moonrise/moonset for Argentina in 2009, I transcribed the rhythms into music. I was delighted that the resulting composition for flute, guitar, violin, bandoneon, piano, and bass sounded to me like an avant-garde Argentine tango.

The process also became a dance between visual and musical elements. Collaged images for the eclipses, suns, and moons were cropped from digitally manipulated photographs of a puddle. Sound wave patterns of the flute became elements of the composition, and the motif of cut squares references the holes found in player piano rolls. The braille music notation offers another layer of language.
To transcribe the patterns into music, I created a 24 hour “ruler” with octaves of a 12-note chromatic scale. After plotting the positions of the sun, moon, and eclipses, I drew lines which translated into the lengths of violin, guitar, and bass fiddle strings.
