Beginning in the 1960s in Los Angeles Channa Horwitz developed a system of permutational drawing that is at once conceptually rigorous and visually rich. In her breakthrough series Sonakinatography—whose title means “sound” (sona), “motion” (kineto), and “notation” (graphy)—Horwitz employed colors and numbers to plot movement over time. The graph paper she used, which featured eight squares per inch, led her to work in sequences of eight.
