Set in D Mixolydian mode (major scale with a flat seventh) and including an Andante and Allegro section, the contrasting harmonies and style set the mood of an enchanted forest where anything can happen. Cellos and basses get to play a question and answer section with the upper strings before returning to a tutti section that leads into the brief contrapuntal ending.Concert/Contest.
