American composer Aaron Copland (1900-90) was instrumental in Ginastera's move to the United States and his international musical activities. Their encounter dates back to 1941, when Copland visited Argentina with support from the Guggenheim Foundation to discover young talent. Copland's compositional style, which combined American music with contemporary compositional techniques, would significantly influence Ginastera. Regarding this piece, Ginastera stated that he attempted to imitate Copland's jazz elements. While the fast passages and syncopated rhythms in the first half suggest the influence of ragtime, characteristics previously observed in Ginastera's works, such as bitonality, are also prominent.
