It has been argued that "there is a paucity of information on women's involvement in sound poetry, whether as practitioners, theorists, or even simply as listeners". Among the earliest female practitioners are Berlin poet Else Lasker-Schüler, who experimented in what she called "Ursprache" (Ur-language), and the New York Dada poet and performer Baroness Elsa von Freytag-Loringhoven. The Baroness’s poem "Klink-Hratzvenga (Death-wail)" was published in "The Little Review" in March 1920 to great controversy. Written in response to her husband Leopold von Freytag-Loringhoven’s suicide, the sound poem was "a mourning song in nonsense sounds that transcended national boundaries". The Baroness was also known for her sexually charged sound poetry, as seen in "Teke Heart (Beating of Heart)", only recently published.
