Mozart composed the divertimento in 1777 for the name day of Countess Maria Antonia Lodron, a family friend and member of the Salzburg aristocracy.
The divertimento is structured in six movements: In 1952 George Balanchine choreographed for his company New York City Ballet a piece titled Caracole to this music.
A few years later, he restaged it for a celebration of Mozart's bicentenary with some changes in score, choreography, costumes and set design as Divertimento No.
