Junior Rock depicts two children, a brother and sister, who despite all their differences are both filled with the joys of life. The piece opens with a lively graceful theme depicting the light and good-natured mood that characterizes the two children playing. The music then becomes more calm and romantic in the middle passage. The piece comes to a cheerful and youthful close with the extended restatement of the earlier thematic material. It has been arranged for beginner bands and can be played with a minimum of six players (+ percussion).
