Emerging from 1960s New York, Edwina Leapman’s paintings pair an abstract expressionist contemplation of the canvas with the spareness of minimalism. Leapman works in a meditative fashion, methodically tracing horizontal lines. As with the work of Agnes Martin, her paintings often recall a ruled page. Prizing the values of balance, serenity, and rhythm, she strives to establish a precise tonal relationship between the colors she uses. “Two colors are like two chords,” she has said.
