As a child Densmore (b.May 21, 1967-d.Jun 5, 1947) developed an appreciation of music by listening to the nearby Dakota Indians. She studied music at Oberlin College for three years. During the early part of the twentieth century, she worked as a music teacher with Native Americans nationwide, while also learning, recording, and transcribing their music, and documenting its use in their culture.
