Ellen Fullman (born 1957) is a composer known principally for music she has written for an instrument she invented, the long string instrument. Fullman studied sculpture at the Kansas City Art Institute. She has performed with the Deep Listening Band and Paul Panhuysen. Tuned in just intonation, the long string instrument is played by walking along the length of incredibly long strings and rubbing them with rosined hands. This produces longitudinal vibrations, and her music explores the nodes of vibration. Her early pieces were notated with choreography.
