This is lively music characterized by upward leaps of octaves. The intent is to depict that boundless energy we associate with youth! The opening measures are markedjagged, with gathering energy as the ensemble sets off on a playful journey. Then, as the work unfolds, there are several interruptions to the main theme -- once in a sprightly 6/8 dalliance, and once in a melodic and reflective passage. This slower section ends with bird calls in the upper winds. Yet, because the fun-loving spirit of the work prevails, the opening theme always returns in one guise or another.
