Her music heralded the emerging modernist aesthetic, and she became a central member of a group of American composers known as the "ultramoderns". She composed primarily during the 1920s and 1930s, turning towards studies on folk music from the late 1930s until her death. Her music influenced later composers including Elliott Carter.
