Channa Horwitz (American 1932-2013) was a contemporary conceptual artist based in Los Angeles. She received a B.F.A. from CalArts in 1972 and made logically derived compositions for fifty years: visually complex, systematic works generally structured around linear progressions using the number eight representing motion across time. She invented a system of composition she called “Sonakinatography,” meaning sound/motion–notation that plots the activity of eight entities over a period of time using numbers, colors, and eight-to-the-inch squares of graph paper. While visually appealing in their own right as stand-alone drawings, Sonakinatography compositions have actually been performed via percussion, dance, spoken word, and acoustic and electronic instruments Recent exhibitions included the 55th Venice Biennale, ZKM Karlsruhe and Kunsthalle Dresden (Germany), Centro Galego de Arte Contemporánea (Spain), Galerie Casas Riegner, Bogota, Hammer Museum, (Los Angeles) and Kunsthalle Düsseldorf.
