Yoko Ono was a skilled, boundary-breaking artist, musician, and filmmaker long before she married musician John Lennon. Classically trained in piano and voice as a child, Ono became the first woman admitted to the philosophy program at Gakushūin University in Tokyo, and she later studied writing and music at Sarah Lawrence College, in Bronxville, New York, though she did not graduate from either. In 1960–61 she was at the center of the New York City avant-garde art scene when she held a series of performances at her Manhattan apartment. There Ono began to make conceptual art pieces that imaginatively encouraged, and often required, interactive participation from the audience. She continued to make art and music throughout her life.
