Buffy Sainte-Marie demonstrates the Mouth Bow while performing “Until It’s Time for You To Go” on TV, 1966

Buffy Sainte-Marie demonstrates the primitive mouth bow, which might be a cousin to another ancient instrument involving twang, the Jew’s Harp (or also known as the jaw harp, mouth harp). After showing how it’s done, she performs one of her best loved songs, “Until It’s Time For You To Go.”
