HORWITZ, Untitled Linear Progression, 1987

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 55^th 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.
