Ivesiana is a ballet choreographed by George Balanchine to music by Charles Ives. The ballet premiered on September 14, 1954, four months after Ive's death, at the City Center of Music and Drama, performed by the New York City Ballet. In the original version, the six sections were "Central Park in the Dark", "Hallowe'en", "The Unanswered Question", "Over the Pavements", "In the Inn", "In the Night". Balanchine later removed the second and fourth sections, and had made many changes to the ballet. The ballet is rarely performed. "The Unanswered Question" is sometimes performed separately.
