Horwitz spent her career creating rigorous, but beautiful, conceptual works on paper. In her Sonakinatography drawings, she developed the idea of expressing sound (sona) and motion (kina) through two-dimensional notation and color. She once said, "As a painter, I could compose in two dimensions, as a sculptress I could compose in three dimensions, but I could not understand how musicians and dancers could compose in the fourth dimension: Time." While she considered her drawings to be her main form of expression, she also conceived them as scores that were open to interpretation by other artists. She submitted this two-part work, which presents its score both numerically and through color, as a proposal to the Laguna Beach Art Museum for a quarter-mile, eight-day installation.
